Applications | Butt, fillet welding of 490N/mm2 class high strength steel and low temperature steel of structure such as ships, bridges, buildings and stroage tanks etc. |
---|---|
Characteristics | 1. CSM-70U is a metal type cored wire for flat & horizontal fillet welding with CO2 gas shielding. 2. Its deposition rate is 10~30%higher compared with a solid wire. 3. It provides excellent usabillity with stable arc, less spattering better beed appearance and less quantity of wleidng fume comparable to solid wire. |
Notes on usage | 1. The optimum flow of CO2 for shielding is 20~25ℓ/min. 2. The distance between tip & base metal is to be 20~25mm. 3. Protect the weld with a screen to prevent blowholes caused by wind where the wind velocity is 2m/sec and more. 4. Thick heavy plate should be welded under proper perheating & interpass temperature. |
