Custom stainless steel welding galvanized plate fabricate

Welding, 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

l  Heat: Different types of materials are also subject to distortion. Warping can also occur if the heat is too high

l  Process selection: In order to avoid the usual problems that come with welding thin metal, you should carefully consider the process

l  Equipment: need to consider the equipment that used and choose the right method to weld.

TIG (Tungsten Inert Gas) welding sheet metal is certainly one of the most common welding methods. This is an arc welding process wit

an infusible 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:

Size of weld: Avoid overwhelming when making a weld seam.

Intermittent welding: Try making breaks instead of a single long weld.

Fewer weld passes: The more weld passes a welder makes the greater the chance of shrinking the materials. Try making less.

Welding placement: You should weld near the neutral axis or the center or the part.

Backset welding: A welder should weld from left to right, placing every weld seam from left to right rather than the opposite way.

Preset parts: Make trial welds before you start the process by setting the parts together.

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.

Thermal stress relief: The process involves controlled heating of the weldment followed by controlled colling afterward.

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.
