MIG-MAG welding technique
Date 06/05/2019
The GMAW welding MIG-MAG is a method of welding using fire-resonant heat between solid-state electrodes through a constant speed wire feeder. In MIG welding, the formation flame is protected by an inert gas
Welding rod technology
Date 06/05/2019
One of the most used welding techniques today is welding rods. The method of welding a cathode-ray tube (SNAW), is the method of using the arc heat generated between the coated rod and the solder to be welded.

How to fix the weld cracks
Date 06/05/2019
In the course of welding, welds are susceptible to defects and deformations if the welders fail to follow the proper procedure nor properly understand the metal properties of the welding material. The most common defects are cracked welds.
The principle of occupational safety in the use of plasma
Date 06/05/2019
At present, plasma cutting methods are increasingly used in metalworking due to the advantage of faster cutting speed on metal surfaces compared to previous methods such as sawing, cutting and cutting off oxygen gas.

In mechanics, metalworking, welding machines are used quite a lot to repair, connect the metal parts together. There are various welding methods such as welding rod, Tig, Mig, Plasma. Tig welding is a highly applied method due to its high welding efficiency, good weld quality and good quality.
How to use Tig welding machine
Date 06/05/2019
For each machine there are different adjustments, but in principle, the following three parameters: arc current, the amount of gas protection, the amount of gas cooling. These parameters are controlled independently on the control panel and are operated before powering on.
