Weld Procedure

Weld Procedure

Fillet weld gages are one example of equipment used to demonstrate final acceptance of welds Only the gages used by personnel performing final inspection need to demonstrate traceability to a national standard " I have not seen these ever to have been certified Can anyone shed some light on where I could obtain a " certified welding gage" in the Welding Procedure Specification When higher preheat is required by the applicable construction code i e B31 1 B31 9 etc that preheat shall be used for production welding Welding on metal that is wet is strictly prohibited wet metal shall be heated until it is at least warm to the touch to assure removal of moisture Specification and qualification of welding procedures for metallic materials Welding Procedure test Part 1 Arc and gas welding of steels and arc welding of nickel and nickel alloys Part 2 Arc welding of aluminium and its alloys Part 3 Fusion and pressure welding of non alloyed and low alloyed cast irons CONCAVE FILLET WELD Definition A fillet weld that sinks in the center Preventive Action 1 Adjust amps/volts 2 Decrease travel speed 3 Maintain appropriate arc length/wire stickout 4 Adjust torch/rod angle 5 Feed more wire into the puddle when manu al TIG welding 6 Increase stop time dwell time on weaved beads 7 The Track Welding Carriage With Oscillator is a track welding carriage designed to produce butt and fillet welds with or without oscillation The carriage can work in PA flat PB horizontal vertical PC horizontal PD overhead horizontal vertical PE overhead PF vertical up and PG vertical down welding positions Vertical Fillet Welding Downhand Fillet Welding STOP SENSOR OPERATION The K BUG is equipped with two 2 Stop Sensors One sensor is placed on the right side of the carriage the other is placed on the left The Stop Sensors are normally open switches that engage or close when depressed Compact Welding Carriage for Continuous Welding The Wel Handy Mini Strong is a compact welding carriage that was designed to go where most welding carriages could not With its 10 inch footprint and impressive pulling capacity of 77 lb it is sure to be found in some of the roughest welding terrain The initial feature of this unit is its Tools and Supplies needed for Welding Program Please note All items will be needed by the second class meeting Medium shade full face shield and headband 5 or equivalent 1 Arc welding shield Auto Darkening prefer Red 1 Clear face shield and headband for grinding Clear cover lenses for the welding helmet 2 May 20 We are attempting to gather all required items to be certified by AISC American Institute of Steel Construction as a certified steel building fabricator and I ran across this requirement in the FAQ& 39 s where someone had asked if even the weld fillet gages needed to be certified here is the quote " 1 3 Do fillet weld gages used for
