Packaging & Delivery

 Welding of medium carbon steel structures and low alloy  steel structures.

Application areas

• Engineering machinery: welding of structural parts of excavators, loaders, and cranes
• Pressure vessels: welding of medium and low pressure storage tanks, boiler pipelines
• Bridge construction: welding of steel structure bridge nodes
• Power equipment: welding of generator sets and transformer casings
• Mining machinery: welding of wear-resistant parts such as crushers and conveyors

Welding process guide

1. Preparation before welding: remove rust, oil and moisture from the workpiece surface, dry the welding rod at 350-400℃ for 1-2 hours, put it in an 80-100℃ insulation cylinder for use
2. Welding parameters (taking 3.2mm welding rod as an example):
Welding current: 90-120A
Arc voltage: 24-28V
Welding speed: 150-200mm/min
3. Precautions: When the wind speed is greater than 8m/s, windproof measures should be taken, and the temperature between layers should not be lower than 150℃ during multi-layer welding
