How To Welding The Pipe

Pipe Welding Positions are referred to as the combination of the different positions of the welder and the job or specimen. In general the pipe welding position is divided into 2 types namely the welding position on the groove joint and the welding position on the fillet joint.

A common welding technique using the SMAW process is to weave your layer beads.

How to welding the pipe. The pipe welding position is divided into 4 groups namely 1G 2G 5G and 6G. On average a pipeline welder can make between 36 and 52 an hour on arm pay anywhere from 15 to 25 an hour for the truck pay and then somewhere between 100 and 150 for the per diem. Joint coating is applied usually a shrink sleeve or mortar diaper.

The rule of thumb is to use one layer of beads for each one eighth inch wall thickness of the pipe. Lets get right to it. When the pipe gets to hot let it cool down or put on a vice grip to lean on.

Pipe welds are made under many different requirements and in different welding situations as per the job nature. In general the position of the specimen is fixed but in many cases it can be rolled or inclined. Welding shall commence only after approval of fit-up by the Engineer-In-Charge.

Make sure you fuse the bevels edge by pushing the toe of the weld into it. Since welding pipe in the 6G position covers all of the pipe welding positions the information on this page can be applied to welding pipe. The pipe welding techniques used and the procedure is also identical to the ASME section IX pipe welding certification.

With all that lets just say for an example on a 60-hour workweek a pipeline welder could be making as much as 5000 for that one week. Pipe-and-Tube-Welding Test Positions are used in pipe welding tests known as. A welded pipe can be manufactured in large sizes without any upper restriction.

Only move forward and side to side with the electrode otherwise the weld will become rough. 1G the horizontal rolled flat position. Defective tack welds must be removed prior to the actual welding of the joints.

For welding Neck and Lap Joint Stub and Flange applications an initial root gap spacing between pipe and flange should be 116 to 18. 5G the horizontal fixed position. 6G the pipe inclined fixed position.

Pipe is laid and welded outside if required. Overlap stringer beads from at least 25 to a maximum of 50. If you cant make a single pass then go with multi-layer beads.

METHODS OF WELDING FLANGES TO PIPE The methods used in welding flanges to pipe will vary according to the type of flange and are basically the same as those used in standard welding practices. Another welding test position known as 6GR inclined fixed position as 6G but with a restriction. This is the intro page about welding pipe and how to pass the AWS B21 6G E6010 open root and E7018 fill and cap pipe welding certification.

The inside weld is made later. To manufacture a welded pipe the first plate or coil is rolled in the circular section with the help of a plate bending machine or by a roller in the case of a continues process. Weld After Backfill is a sequence used to improve overall installation rate for steel pipe.

Ad High Performance Wide Range Structural Adhesives Bonding Plastic and Metal. 2G the pipe vertical horizontal weld position. 3 tacks for 2 12 and smaller dia.

6 tacks for 14 and larger dia. Once the circular section is rolled from the plate the pipe can be welded with or without filler material. 4 tacks for 3 to 12 dia.

Pipe is backfilled.
