The heating phase sometimes referred to as bead up is where the pipe ends are pressed against a heated plate.

How to weld a pipe to a plate. A method of welding a pipe to a pipe plate conprises slipping a ring over the pipe the adjoining surfaces of the ring being in contact with the pipe surface and with the pipe plate surface over the entire circumference inserting the pipe end over a short distance into a bore in the pipe plate rolling the end of the pipe against the bore wall whereby a clamping contact between the pipe end and the bore wall is achieved and welding the pipe end to the pipe plate. So I used a hard rock to feathertaper the start on the bottom before welding the second hald of the joint. The end of the pipe must first be cut square.

Flat Welding Position 1G and 1F. Prop your finger on the tube so your not trying to slide around the bench or plate. Scribe a line around the pipe and cut grind or file to that line.

For larger pipe use the I beam. TIG Welding Aluminum Fabrication - Sheet Metal Forming - 2 Ovals into 1 Round - Y-pipe - Duration. The main thing on my mind was a question I got from a viewer about making joints like this leakproof.

The details are as follows Dia of Pipe 48 Wall thickness 127 mm Test Pressure 70 Psi Plate material going to use S275JR Deatil is attached in the sketch Please help. Pipe to plate weld selection. I want to calculate the plate thickness and weld thickness of a plate going to use for hydro testing.

This works fine even if you have the plate and pipe at an offset or even if the pipe is at an angle with straight pipe ends At least it works in AIS 2008 dont know if. In order to keep the outside OD surface of a welded pipe smooth and uniform a cutting tool called scarfing blade is used to remove the weld flash. Working with the example provided by the preceding sketch ie 3 inch schedule 40 pipe with 12 inch plate and a required fillet weld size equivalent to a 14 inch fillet weld.

For example SA53 or SA106 pipe and SA36 plate are all contained in the P1 group ASME or M1 for AWS B21. 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. The pipe welding position is divided into 4 groups namely 1G 2G 5G and 6G.

They are generally forged type with Hub. If a scribe line is made on the flat plate 1-inch from the root the fillet leg against the plate can be measured with a ruler. In the ERW and EFW manufacturing process welded pipes are formed by hot or cold rolling plate and welding the seam.

Wrap a piece of heavy paper around it tightly aligning the edge of the paper. These flanges are welded on inside as well as outside to the pipe. Slide your finger around the diameter of the tube as you weld to maintain the angle.

Below are the flanges based on the pipe attachments. For small pipe use the angle iron. Groove and Fillet Welds There are four welding positions for plate and four positions for pipe.

If possible drill a hole in the plate centered on the pipe and run threaded rod through the plate and pipe to clamp it for welding. Because maintaining alignment is essential during the welding. To achieve this a bevel is made on the end surfaces of the elements to be assembled prior to welding them together.

Try using angle iron a piece of I beam as a jig for aligning and holding your pipe in place as you weld. Classification of flanges based on pipe attachment 11 Slip-on Flanges. Sep 14 2007.

In option 2 both the V and M get transferred to horizontal shear and the P value is vertical shear in the welds. As measured from the scribe line the dimension to the fillet toe should be less than 34 inch requires a 14 inch weld. Welding thick parts together plates and pipes requires the weld be made over the total thickness of the part in order to guarantee the assemblys mechanical continuity.

They can also be fabricated from plates but without Hub. Hi Kevarnold If you have a groove between the pipe and the plate you can use the groove weld to fill the gap and then use the fillet weld to build your weld. It is unlikely the pipe and the plate will have the same specification unless the pipe is fabricated from plate.
