What is arc welding and how to make arc

When the tip of the welding rod contact with the surface of the welding material, it will produce short-circuit phenomenon and at the contact point will be very high temperature. Then, when most rods are welded out of the weld at a certain distance, that air becomes conducive and produces electricity that produces heat and strong light.

It is as other electrical appliances, welding machines also deals with unvoidable problems and malfunction. In case it is simple failures, you can fix immediately without going to shop for reparation or warranty that can make your work interruped. Some popular problems, causes and solutions about welding process below :
Weld quality testing methods

Weld quality testing methods

There are two methods of test of the quality of welds: destructive testing and non-destructive testing.
Electric Arc Welding Technology: Guide to vertical welding

Electric Arc Welding Technology: Guide to vertical welding

Due to the impact of gravity, the molten metal is easy to be out of the weld pool, the weld pool is located on the vertical plane so the weld in the standing position is difficult to form. Standing welds are prone to defects such as lumps and sagging. Bottom-up welding make the weld less slag. It is relatively difficult for the craftsman to work in places where the weld is placed at low height. In this condition the molten metal is likely to fall down. So be careful!

Types of welding rods in arc welding technique


In welding (rod welding) technology, in order to form welds, the welder must take welding rods that meet the following requirements:
Stainless steel welding machine and guide how to choose stainless steel welding machine

Stainless steel welding machine and guide how to choose stainless steel welding machine

SUS201, SUS304 are two popular types of stainless steel in the market today and are used for a variety of purposes. However, for any purpose, it also has to undergo the operation such as cutting, welding, ... The following will guide you how to choose the stainless steel welding machine to meet the needs of work.
Tig welding technique do not use stick or self-made offset stick

Tig welding technique do not use stick or self-made offset stick

The Tig welding technique does not use a stick or self-made offset as a method applied for very thin materials such as motorcycle parts, casing of X-ray machines and medical equipment.
It requires high weld, no deformation or roughness inside the material. If welding rods are used, high currents (at least 30A) should be used, as if the temperature is too low it will not melt the stick and distort the welding material, resulting in ineffective welding .
Selection of size and grinding electrodes in Tig welding

Selection of size and grinding electrodes in Tig welding

In the Tig welding technique, electrodes are used with a diameter of 0.25 - 6.35mm, a length of 70-610mm and surface cleaned with a solution or grinded. After pulling strings or bars, the surface will be cleaned with appropriate solutions. Grinding means that the surface is cleaned by electrode grinding.
Material Used in TIG Welding

Material Used in TIG Welding

In Tig welding, material used as shielding gases. However Helium and Argon are more popular in usage because of its reasonable price and the abundant natural gas reserves.
