Application of Temperature and Humidity Recorder in Planting of Water Spinach

Water spinach is a relatively common vegetable and a common cultivar in vegetable cultivation. The growth of water spinach prefers a warm environment, and the temperature and humidity have a great influence on its growth. Therefore, in the process of planting management, special attention should be paid to the change of temperature and humidity. The temperature and humidity recorder is an agrometeorological instrument that can automatically detect and record air temperature and humidity. With this instrument, it can scientifically prevent temperature and humidity hazards, protect the water spine planting, and improve production and quality.

For a spinach that prefers to grow in a warm environment, if the crop continues to grow in a relatively low temperature environment with relatively high humidity, it will inevitably affect its growth quality, especially in the sowing and seedling stage. This effect is particularly obvious. The temperature and humidity have the benefit of seed germination, and if the temperature is too low, it will cause freezing damage and reduce the germination rate. In addition, high temperature and high humidity create favorable conditions for the occurrence and spread of diseases. If the temperature and humidity are too high, the plants will cause pests and diseases and endanger the growth of crops. Therefore, in the management of water spine planting, it is essential to strengthen the management of temperature and humidity. The application of temperature and humidity recorder provides powerful technical support for the monitoring of temperature and humidity environment.

The temperature and humidity recorder is used to strengthen the monitoring and management of the temperature and humidity environment in the greenhouse environment, so that users can obtain temperature and humidity data in time and accurately, prevent and prevent it in advance, and at the same time, through scientific management, it can also promote crop growth and improve planting. The output and quality show that meteorological instruments are not only “protectors” but also “blazers”, which play an important role in promoting stable production and efficiency of agriculture. At present, meteorological instruments such as temperature and humidity recorders are widely used in vegetable cultivation, orchard, tea garden management, facility agriculture and many other fields.

Welding Sheet Metal
Sheet Metal Welding
Welding, by definition, is the process of joining two metals together by heating the metal surfaces up to their melting points. However, the process of welding isn`t as simple as it sounds. Welding is a highly technical process, with numerous types and techniques that only skilled personnel are able to understand and practice

Considerations for welding
Heat: Different types of materials are also subject to distortion. This is the case with thinner ones. Warping can also occur if the heat is too high
Process selection: In order to avoid the usual problems that come with welding thin metal, you should carefully consider the process you are using.
Equipment: need to consider the equipment that used and choose the right method to weld.

Welding sheet metal methods

MIG Welding

What is MIG welding?
Metal Inert Gas (MIG) is also known as gas metal arc welding (GMAW). This type of welding is basically an arc welding process that joins two metals. This is done by heating the metals with the help of an arc. This arc is formed between the surface to be welled and a continuously fed filler electrode. This type of welding uses a shielding gas to protect the molten pool of weld metal from reacting with elements present in the atmosphere. MIG welding requires a DCEP (Direct Current Positive Electrode), also known as Reverse Polarity

What Metals Can Be MIG-Welded?
One of the major reasons why MIG welding is so common is that it can be used to weld any metal (almost). Although the weld quality from MIG welding is not superior to other types of welding, MIG welding is one of the fastest and the most cost-efficient welding processes. Moreover, MIG welds are great, if not perfect.
The metals that are most commonly welded by this type of welding include stainless steel, carbon steel, and aluminum, with carbon steel being the easiest metal to MIG weld.

Applications of MIG Welding
Some of the most important applications of MIG welding are listed below:
a)The most common application of MIG welding is in the automotive industry. No matter what the size of the vehicle is, MIG welding is employed for automotive repairs. The reason why MIG welding is the top choice for automotive repairs is that it provides sturdy and robust welds up to a mark of 0.5mm.
b)It is used in sheet metal welding
c)MIG welding is used in pipe welds. Not only does it form efficient and long-lasting welds but it also saves on time and cost

Advantages of MIG Welding
The use of MIG welding is widespread for all the right reasons – high-quality welds for non-ferrous and ferrous alloys at a fairly low price. It is associated with numerous benefits:

a)It has the ability to join many types of materials
b)It can join materials of different thicknesses
c)The equipment components are simple, and thus, readily available in the market at very affordable prices
d)The electrode efficiencies of MIG welding are higher (92-98%) as compared to other types of welding
e)MIG welding is associated with higher operator factor and welder efficiencies
f)It can be easily adapted for hard automation, high-speed robotic, and semi-automatic applications
g)MIG welding comes with the capability of all-position welding
h)The appearance of weld bead formed from MIG welding is excellent
i)The hydrogen weld deposit in MIG welding is lower
j)It requires a lower heat input as compared to other types of welding
k)The slag and weld spatter is kept at a minimum in MIG welding, which makes the cleaning of the weld easy and quick
l)Less amount of welding fumes are produced in MIG welding which makes it safer for welders
m)The cost of weld metal/ length deposited is lower making MIG welding a cost-effective welding process
n)The skill level needed for MIG welding is lower than what`s needed for other types of welding, making it suitable for beginners
o)The welding wire in MIG welding runs continuously with lesser downtime for electrodes replacement
p)MIG welding is excellent for tack and spot welds
TIG Welding for Sheet Metal
TIG (Tungsten Inert Gas) welding sheet metal is certainly one of the most common welding methods. This is an arc welding process with an infusible (tungsten) electrode, protected by inert gas (the gases most commonly used are argon or helium), which can be performed with or without filler metal
What is the thinnest sheet metal that can be welded?
A welder should approach welding thin materials with caution. You should also take into account the type of material and the welding process you are planning to implement. Gas metal arc welding (GMAW) is a very effective method in joining together thinner materials. So, for instance, you can work on 18-ga. to 0.1875-in. stainless steel or 24-ga. to 0.1875-in. carbon steel.
How do you stop a weld distortion?
Sometimes when welding sheet metal, distortion can occur due to the thickness of the material. Even something minimal likes to patch a panel can end up with devastating effects. The best way to prevent this is to avoid creating distortion as much as possible.
Some methods include:
ï‚·Size of weld: Avoid overwhelming when making a weld seam.
ï‚·Intermittent welding: Try making breaks instead of a single long weld.
ï‚·Fewer weld passes: The more weld passes a welder makes the greater the chance of shrinking the materials. Try making less.
ï‚·Welding placement: You should weld near the neutral axis or the center or the part.
ï‚·Backset welding: A welder should weld from left to right, placing every weld seam from left to right rather than the opposite way.
ï‚·Preset parts: Make trial welds before you start the process by setting the parts together.
ï‚·Use clamps: Clamps are a good way to use instead of a tack weld. You simply clamp down the parts and set them in the desired way before you start welding.
ï‚·Thermal stress relief: The process involves controlled heating of the weldment followed by controlled colling afterward.
ï‚·Minimize welding time: The more time you take to weld a panel the greater the chances are of creating distortion. Simply try shortening the time needed to weld
