Wearshield® BU-30美国林肯堆焊焊条,焊接性能优良,质量稳定可靠,工艺性突出,Can be used both downhand and out of position, although the flat position is preferred
Arc characteristics are excellent with very low spatter levels
The electrode coating permits the use of the drag or contact welding technique
Good arc restriking,Wearshield BU 30 produces a crack-free wear resistant deposit with a hardness of 31-38 HRc (295-350 HB) depending on dilution and
number of layers. It is particularly suitable under conditions of moderate abrasion and friction, combined with resistance to impact. Ideally
suitable for APLs involving rolling, sliding and metal to metal wear. It may also be used as a final overlay on parts which need to be
machined or as a build-up layer for other hardfacing materials.
