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 The illustrations above show you how to test a 1/2″ fillet Slide the gage and have the top end rest against the vertical piece This end should be exactly at the top edge of the weld to be a 1/2″ fillet If there is space between the gage and the toe of the weld then the weld is undersized Manual welding Welding with the torch gun or electrode holder held and manipulated by hand Accessory equipment such as part motion devices and manually controlled filler material feeders may be used An example is SMAW or GTAW Semi automatic welding Manual welding with equipment that automatically controls one or more of the welding Jun 07 The thickness of 1 6 12 7 mm can be welded and there is no need to prepare their edges The metal of 6 4 25 4 mm thickness requires edge preparation and can weld in a single pass Thickness is practically unlimited with this procedure when the multiple pass technique is used The horizontal fillet can make up to 9 5 mm weld in a single pass 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 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" These welds provide smooth transition to weld metal after grinding Connected elements in a T joint should be brought into as close of contact as possible before joined with fillet welds The increase in gap leads to a decrease in throat and is not apparent visually Aug 11 These Welding carriage are used for Automatic Welding of Fillet Butt Joints in different Welding Position GMAW/FCAW process is normally used along with these kind of carriage These carriage uses permanent magnet to hold on to the Job and can be used in different Welding position depending on the Tractor Force of the magnet used […]The welding coordinator prepares a preliminary welding procedure specification pWPS which is an initial proposal for carrying out the procedure test For each joint configuration either butt or fillet weld consideration is given to the material grade and thickness and anticipated fit up tolerances likely to be achieved in practice
