The welding residual stress is caused by the uneven temperature distribution of the weldment caused by welding, the thermal expansion and contraction of the weld metal, etc., so the welding constru...
Harmful factors of welding materials
(1) The main research object of welding labor hygiene is fusion welding, and among them, the labor hygiene problems of open arc welding are the biggest, and th...
ER70S‑6 conforms to AWS A5.18. The designation breaks down as follows:
ER – Electrode or filler rod
70 – Minimum tensile strength of the deposited weld metal: 70,000 psi (~490 MPa)
S – Solid wire
6...
Choosing the right welding wire is crucial for achieving strong, clean, and efficient welds. Two of the most commonly used welding wires in steel fabrication are Solid Wire (ER70S series) and Flux...
1. What is arc striking? What are the ways to start an arc? What should you pay attention to when striking an arc?
The process of igniting and producing a stable arc is called arc ignition. There...
In GMAW (gas metal arc welding) practice, horizontal welding is a position that many beginners have mixed feelings about. It’s easier than vertical or overhead welding, but if parameters an...
