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.
Production Information of Automatic Weld Overlay
