The position in which the structure is found and the position where the part will be used are both where welding is done.

Welding can be done in any position.Some welding processes have all-position capabilities, while others may only be used in one or two positions.

The position of the welded joint on the plates or sections being welded can be classified according to position.

A number is used to define the position and an F for Fillet or G is the type of weld.

The upper side of the joint is used for this type of welding.The face is horizontal.

The axis of a weld is a line through the length of the weld to the center of gravity.

In order to make satisfactory bead welds on a plate surface, the flare motion, tip angle, and position of the welding flame above the molten puddle should be carefully maintained.

The welding torch needs to be adjusted to give the right type of flame for the metal being welded.

By raising and lowering the welding flare with a slight circular motion, narrow bead welds are made.

The angle of the tip should be 45 degrees.The flame will be pointed at the welder.

Increasing the angle between the tip and the plate surface is one way to increase the depth of fusion.

The flame will burn through the plate if the puddle is too large.

A properly made bead weld will be below the upper surface of the plate.A bead weld shows a build up on the surface.

When making a bead weld with a welding rod, a small puddle should be formed on the surface.The base plate and rod are melted together after the welding rod is inserted into the puddle.The torch should be moved to get good fusion.The amount of metal deposited from the welding rod can affect the size of the bead.

The plates should be aligned using tack welds.The lighter sheets should be set in a certain way to prevent warpage.

The position of the welding rod and torch tip is shown in the figure.

The welding rod should be enough to produce a puddle of the desired size if the flame motion is controlled.

A molten puddle of a given size can be carried along the joint.This will ensure that there is enough metal for reinforcement at the weld.

The molten puddle needs to be taken care of.This will result in low strength in the weld.

The complete definition of horizontal welding is determined by the weld type.

The welding is done on the upper side of the horizontal surface and against the vertical surface.

Butt welding is more difficult to master than flat position.molten metal tends to flow to the lower side of the joint.The torch's heat goes to the upper side of the joint.It is difficult to apply a uniform deposit to this joint.

Attach the plates at both ends.The heat should be distributed equally to both sides of the joint by moving the torch up and down.The flow of metal to the lower side of the joint is prevented by this.A joint in horizontal position will require a lot of practice.It is important that the technique is mastered before moving on to other types of welds.

molten metal tends to pile up when welding on a vertical surface.

The flow of metal can be controlled by pointing the flame upward at a 45 degree angle to the plate and holding the rod between it and the molten puddle.

Good penetration and fusion at the joint is ensured by the manipulation of the torch and the filler rod.

A uniform bead should be deposited by the torch and welding rod.The welding flame should sweep molten metal across the joint to distribute it evenly if the welding rod is held above the centerline.

For welding in the flat position, butt joints should be prepared the same way as those for the vertical position.

In overhead welding, the metal tends to fall on the plate, causing the bead to have a high crown.

To get good fusion with some reinforcement at the bead, the molten puddle should be kept small.The flame should be removed for an instant if the puddle becomes too large.

When welding light sheets, the puddle size can be controlled by applying the heat equally to the base metal and filler rod.

To melt the edges of the joint, the flame should be directed.Adding enough metal to maintain an adequate puddle is necessary.

The welding flame should support molten metal and small welding avoid burning from one place to another.

Only a small puddle is needed, so a rod should be used.The heat should be controlled through the plates.

In different welding situations, pipe welds are made.The welding position is determined by the job.

Flat-position work can be done if the position is fixed.There are positions and procedures for welding.

Attach the pipe to the rollers with steel bridge clamps and Align the joint and hold in position.Start at point C and move upward to point B.When point B is reached, move the pipe clockwise until the stopping point of the weld is at point C.The torch should be held between points B and C when the pipe is rotating.

The position of the torch at point A is similar to a vertical weld.The angles of application of the torch and rod are altered slightly to compensate for the fact that the weld assumes a nearly flat position when point B is approached.

Just before the root of the starting point, the weld should be stopped.The area surrounding the junction point is reheated so that it is at a uniform temperature.This will ensure a complete fusion of the advanced weld with the starting point.

If it's more than 1/2 in.A multi-pass weld should be made.

The tack welds are oriented approximately as shown below after the pipe is set up.The pipe must not be moved in any direction after welding is done.

The welds are made in two stages.Start at the top and work down one side to the bottom to join with the other side.The higher the temperature of the electric arcs, the more effective the welding downward method is.The upward welding method has a speed of three times that of Arc welding.

The backhand method is used for joints in low carbon or low alloy steel piping that can be rolled or are in a horizontal position.One pass is used for the wall thickness.There are two passes for wall thicknesses.Three passes for wall thicknesses of 5/8 to 7/8 in.Four passes for wall thicknesses from 7 to 8 in.The measurement is 2.22 to 2.87 cm.

The backhand method is used to welded the pipe in this position.The weld is carried around the pipe.

The root bead is started at the bottom of the grooves if a lineup clamp is used.Care should be taken to build up a small bead on the inside of the pipe when there is no backing ring.The root bead should be carefully fused if a backing ring is used.Before the lineup clamp is removed, root bead should be applied.The bead needs to be completed after the clamp is removed.

In order to remove any undercut by the deposition of the root bead, the filler beads should be fused into it.There are usually at least one or more beads around the pipe.

The finish beads are applied over the filler beads to complete the joint.This is a weave bead.The width is 1.59 cm and the depth is 1/16 in.When complete, the pipe is above the outside surface.The finished weld can be seen in view D.

Special joint details have been developed for aluminum pipe.A backing ring isn't usually used.When fluids are transmitted through the piping system, the rectangular backing ring is rarely used.It may be used for structural applications in which pipe and tubular members are used.

Long Island is a 118 mile stretch of land that starts off the coast of Manhattan and goes deep into the Atlantic ocean.As he set out to work with a variety of metals, he had always been interested in welding from an early age.
