Ensure the edges to be joined are smooth by grinding the surface before actual welding.

How to welding a pipe. Welding the Root Pass Before beginning to weld the pipe the procedure should be checked to assure that the correct electrode is being used. The work area must be clean. 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.

Its very important to cut the exhaust pipe in the right measurement. Tacking the pipe is done by placing the filler wire into the grove and going over it with the TIG torch. This and other welding prep work is key in high-purity pipe welding.

The pipe welding techniques used and the procedure is also identical to the ASME section IX pipe welding certification. Welded Pipes are manufactured from Plate or continues Coil or strips. Use a drag angle that is somewhere between 5 and 10 degrees.

The initial step is to cut the exhaust pipe. This includes the diameter and the classification of the electrode. Make sure the pipe is not angled in any direction when it is being placed into the Pit Bull.

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. Pipe welding applications require quality and consistency. Ensuring you stick to a crescent moon motion the moon should be looking down move back and forth over the gap.

One common method that I have used on pipelines in the oil and gas industry is to create a magnetic coil with the work lead. Welded Pipe Manufacturing Process. End of the pipe.

If you will be using a 18 filler wire you will set the gap with a 18 filler wire. 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. Proper cleaning joint preparation and part fit-up help ensure access to the joint and the necessary penetration and weld strength.

Lets follow the four easy steps and weld exhaust pipe properly. I wrap the lead around the pipe three to six times about half the pipe diameter away from the weld groove on the opposite side from the direction of the arc blow pull. The most common type of joint used for welding together pipe is a butt joint.

At a minimum high-purity pipe welding should involve the following preparation. A pipes interior can be electropolished after welding by filling the interior volume of the pipe with the electropolishing solution. Once gravity takes hold.

Start welding in the middle of the tack weld. One turn after the pipe is clamped is tight enough. Place one pipe in the McElroy Pit Bull and fasten it down tightly.

To tack the pipe you want to find a spot that the filler wire cant slip through the grove. If you want to fit the pipe to another pipe the measurement must be. Ad High Performance Wide Range Structural Adhesives Bonding Plastic and Metal.

But you should always lay a bead over a cleaned weld to avoid slag being deposited in the filler material. A common welding technique using the SMAW process is to weave your layer beads. Preparation is a critical step in pipe welding.

Cut The Exhaust Pipe. The welding con-sumable should be selected to correctly match or overmatch the strength of the pipe. Then simply tack the pipe.
