Brazing Wire Messer MG 240 Cast Iron 6.0mm
PRODUCT ENQUIRY
Description
Messer MG 240 B are rod for brazing and oxy-fuel welding of cast irons
General Characteristics:
MG 240 is a bare rod intended for the repair and joining of cast irons by oxy-fuel processes rather and conventional welding techniques.
Deposits are easily machined and match castings in both color and rusting, making repairs virtually undetectable.
Applications:
Torch welding for maintenance and production of heavy and light castings.
Commonly used on parts where color match is critical such as filling of surface defects and building up worn or missing sections.
Also used to repair machine bases, manifolds, engine blocks, cylinder heads and gear housings.
Tensile Strength/276 N/MM2
Working Temperature/870C
Hardness/Approx. 200 HB
Procedure:
Bevel heavy sections to form a 75° vee. Always use a slightly carburizing flame to prevent porosity due to oxidation of carbon. Preheat part to 430°C before starting to weld. When using bare rods heat end of rod, dip in MG 240 flux and transfer to weld area. Melt off a small amount of rod, continue heating until deposit flows out. Add filler metal a drop at a time making sure each deposit is fused to the base metal; use sufficient flux for good cleaning and protection. After welding allow part to cool slowly to prevent hardening and cracking.
