Looking for info on the best process to weld T1. I have some plates the are 1 1/2" thick (t joint). Looking for preheat numbers and if it is possible to weld with solid wire.(Best wire choice)(Joint prep)(Post heat) This is for a low boy trailer app. I am building a member that will attach the rear jeep to the trailer deck. The trailer will carry upwards of 55 tons. Thanks Shane Sawyers
