Subject: Re: mig welding root pass Author: Stiv9 [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 15:21:11 05/21/08 Wed In reply to: ryan 's message, "mig welding root pass" on 08:53:15 05/17/08 Sat I do not think you would reach good result welding uphill... I recommend following: - use 1.0 mm diameter, - use 3.5-4 m/min, 16.5 V, - use 82%Ar+18%CO2 mixture, - go DOWNHILL! - do small weaving if necessary You will not achieve good penetration but you will make good support for filling passes with Flux cored wire in the class E71T-1, 1.2 mm diameter. Use 8 m/min, 25 V, go UPHILL! I am sure you will pass any test! [ Next Thread | Previous Thread | Next Message | Previous Message ]
