The analysis of the 1 machine welding repair technology.
Preheat to 550 ℃ - before welding
After weld repairs heat preservation 5-650 ℃,
Eight hours.
2.
Artifacts no preheating before welding, after welding heat preservation 3 -
4 hours.
Two ways are easy to crack, hard point, not easy to do mechanical processing after welding repair.
Electrode is cheap.
With nickel base cast iron welding rod Z308 welding rod welding, welding and welding layer should be suspended between cooling below 60 ℃, weld zone less porosity, crack, machinability, outstanding high bonding strength, no fall off appearances, because after lapping machine guide rail processing oil absorption and the influence of electrode blow force, prone to bite edge, constitute a 'weld marks', weld area have very different colour and parent metal, and electrode is expensive in this article, reprinted from laser cutting machine
