ASME Standard Automatic Weld Overlay Pipe /steel tube
The advantages of surfacing method compared with other surface treatment methods are as follows:
1) The combination of overlay and base metal is metallurgical combination, with high bonding strength and good impact resistance.
2) The composition and performance of the overlay metal are adjusted easily. The conventional formula of arc welding electrode or flux core electrode is very convenient. Various alloy systems can be designed to adapt to different working conditions.
3) The thickness of overlay is large, and the thickness of the overlay layer can be adjusted within 2-30mm, which is more suitable for severe wear condition.
4) It can save cost and economy. When the base of workpiece is made of common materials and the surface is overlaid with high alloy, it not only reduces the manufacturing cost but also saves a lot of precious metals. In the process of workpiece maintenance, the welding alloy is reasonably selected and the surface of damaged workpiece is repaired by overlay welding. It can greatly prolong the life of the workpiece, prolong the maintenance period and reduce the production.
5) Because the welding technology is to increase or restore the size of parts by welding, or to obtain alloy layer with special properties on the surface of parts, it is not difficult and operable for the personnel who can master the welding technology skillfully.
