How to Select Welding Materials for Dual-Grade Austenitic Stainless Steel
—In The Case of 304/304L and 316/316L
The key to selecting dual-grade stainless steel welding consumables lies in understa...
Introduction
Aluminum welding requires the right filler material to ensure strong, crack-free joints and excellent corrosion resistance. Among the most widely used aluminum welding rods are E4043...
Vertical welding with stick electrodes gives many welders trouble. The molten metal wants to drip downward, the puddle sags, and the bead ends up uneven. But vertical welding is not as hard as it...
Important structures such as boilers and pressure vessels require safe penetration of joints, but due to limitations in structure size and shape, double-sided welding is sometimes impossible. A sp...
1. Core principle: Why must we use argon?
During the welding process, the metal is like red-hot iron at high temperatures. If it is not protected, it will immediately combine with the oxygen and ...
