In GMAW (gas metal arc welding) practice, vertical welding is a real challenge for many welders. If you’re not careful, the molten metal drips down, the weld bead looks like a bunch of berr...
In today’s world where welding technology is changing with each passing day, Shielded Metal Arc Welding (SMAW) is still active in the industrial field with its vitality. From steel structure...
One of the most frustrating moments for a beginner welder is striking an arc only to have the electrode stick to the workpiece. It sticks, glows red, and you scramble to twist it free. Don’t worry...
In steel structure fabrication, flat position welding is the most basic and commonly used position, and it is also the easiest to achieve good weld quality. Although flat welding is relatively les...
The welding electrodes that leave the factory have been dried at high temperature and packaged with moisture-proof material, which usually prevents the coating from absorbing moisture. However, dur...
In multi-pass and multi-layer welding, temperature control between each bead and layer is crucial. This is the “interpass temperature” under discussion. Interpass temperature refers t...
