What is welding sequence?

Welding sequence is the order in which welding beads are placed in a welding joint and is useful for distortion control. By properly planning the sequence in which various weld passes are made, the welder can reduce or eliminate distortion.

What is a weld buildup sequence?

In a Weld Buildup sequence, weld beads or weld passes are welded to suit the base material or weld joint configuration. This is similar to a multipass weld deposit. Cascade sequence is a combined longitudinal and buildup welding sequence by depositing the weld beads in overlapping layers.

What factors should be considered when planning a welding sequence?

There are many factors to consider when planning a welding sequence, such as the type of metal being welded, the thickness of the metal, the desired final shape of the joint, and any special features that need to be taken into account. In general, however, there are a few basic principles that should be followed.

How to weld a primary seam bead?

... primary seam bead shall be welded by subsection back welding method. When welding the middle plate of tank bottom plate, it shall be carried out in the order as shown in Figure 2: Follow the welding sequence and direction shown in the figure above to perform segmented reverse jump welding.

What is a block welding sequence?

In a Block Welding Sequence, welding is carried out in a pre-planned sequence. They are deposited in blocks with steps with intermediate gaps that is filled after previous weld blocks are completed. An example of a block sequence is shown in the below figure.

What is a wandering block welding sequence?

The order in which the increments of weld metal are deposited. This is similar to the buildup sequence. A longitudinal welding sequence wherein the weld bead increments are deposited at random. Whereas, in the Wandering Block welding Sequence, successive blocks of welds are deposited at random distance one by one.
