Types of welding distortion and measures to reduce welding distortions

Date 06/05/2019
Distortions or warping are occurring due to uneven shrinkage between the base metal of the weld and the base metal during heating and cooling during welding and after welding.

Technique for welding CO2 with core wire

Date 06/05/2019
Advantages of welding CO2 technology with wire core is improving the quality of welds, defects at the foot of welds such as: not flooding, flowing ... are minimized, avoiding the need to work.

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.

Welding technology for highly active metals and high melting temperatures

Date 06/05/2019
In terms of welding properties, these metals (Zn, Hf, Nb, Ta, Mo, W) can be divided into two groups. Highly active...

Basic Titan welding techniques for beginners

Date 06/05/2019
Titan welding methods are increasingly popular and applied by the advantages of welding quality as well as aesthetics.

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.

Working principle of TIG welding machine

Date 06/05/2019
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.
