1/8" ZENA NoGas Aluminum Arc Welding Rods (Model ZR.ALA.1.8-1/2 lb. Box)

الوصف

These special aluminum welding rods are perfect for welding, repairing cracks, and building up missing sections of: Aluminum sheet metal, truck beds, bodies, and frames, loading ramps and docks, engine and motor blocks, machine bases and supports, pipe railings, banisters, stairs, diamond plate, transmission housings and gear boxes, irrigation piping, bus bars, electrical switch boxes and mounts. --- Mechanical Properties: Tensile Strength 34,000 psi (250 N/mm2) Yield Strength 20,000 psi (150 N/mm2) --- Elongation 18% --- Current Type/Polarity: DC reverse polarity (electrode positive) --- Recommended Amperage: Min 70 Max 120 --- Typical Applications: -- Truck body/frame repair/fabrication, - Cafeteria equipment repair/fabrication, - Loading ramps/dock repair/fabrication, - Engine and motor blocks/cylinder head repair, - Repair and fabrication of machine bases and supports, - Repair and fabrication of pipe railings, banisters, stairs, diamond plate, - Transmission housings and gear box repair/fabrication. - Repair and fabrication of irrigation piping, mixers, paddles, vats, - Repair and fabrication of electrical bus bars, electrical switch boxes and mounts. --- Recommended Welding Techniques: - OK for flat, horizontal and vertical applications. - Clean weld area by removing oil and grease and by wire brushing and/or sanding/grinding the immediate weld area just prior to welding. - Chamfer edges of plated to be joined and open/chamfer cracks and/or holes to be filled. - Preheat heavy sections broadly. - In thick to thin joining, preheat heavier member. - For multi-pass work, it may be necessary to reduce amperage as base metal temp. increases. - A close arc should be maintained. - Feed electrode quickly and move fast. - When picking up each bead, weld into the previous crater before continuing. - Upon cooling, slag/flux can easily be removed by chipping/brushing/sanding/grinding.
