Product Q&A
Q:What is the maximum operating temperature for this welding wire?
A:
The surfacing metal can maintain good abrasion resistance and corrosion resistance at temperatures up to 650 degrees Celsius.
Q:What are the recommended welding parameters for this electrode?
A:
It should adopt DCRP (Direct Current Reverse Polarity). Reference currents are 120-160A for 3.2mm, 140-190A for 4.0mm, and 150-210A for 5.0mm.
Q:Do I need to preheat the workpiece before welding?
A:
Yes, according to the size of the tool and parent material, preheating to 300-600 degrees Celsius is required, using small current and short arc welding.
Q:What post-weld heat treatment is recommended?
A:
After welding, the part should be tempered at 600-700 degrees Celsius for 1 hour, then cooled in dry hot sand or plant ash to prevent cracking.
Q:What is the hardness of the deposited metal?
A:
The hardness of the ERCoCr-A deposited metal is typically 40-45 HRC, though other variants in the series range from 20-59 HRC.
