SOLUTIONS with Effective, Powerful Advice

Which Process Next?

Additional-processes increase the range of jobs you may accept.

As a welder, why should you be interested in Additional-Processes?

Consider that you may need only minor adaptations to what you already know.

You are prepared to easily learn and master new and different joining techniques.

And you have already safety knowledge and habits of precautions.

The training you got, to perform your main and accepted welding tasks, is a major benefit to build on.

The more Additional processes you master, the greater your versatility and your worth.

Then you can select more rewarding jobs for your benefit.

Additional processes cover a range of joining, surfacing and cutting technologies.

They have some relationship to welding, or were developed using modified welding equipment.

This page on Additional processes is an introduction to some specialized technologies that we present in separate pages.

You will find them linked to hereafter, providing useful information to our interested readers.

Additional-processes Suggestions

The first page we propose deals with Pipe and Tube Welding.

No new processes are usually involved in this class of welding.

Nonetheless unique requirements make this branch a specialized one.

One should be aware of the meaning of Code clauses applied.

Specific process expertise and advanced skills are required.

Most exacting nondestructive testing techniques are applied.

Successful results of special mechanical properties (impact resistance) may need to be demonstrated.

Pipelines are built to deliver fluids under pressure even to great distances, with no leaks and under most difficult climatic conditions.

Therefore their workmanship must be high class, beginning with proper fit-up and tack welding and continuing with qualified welding procedures.

Next in this Additional processes page is that on Micro Welding.

It needs special equipment built to provide limited heat inputs, through fractional current tightly controlled.

Miniature devices, medical implants and jewelry are examples of applications performed under a microscope for exact location.

Also required are proper skills for precise manipulation of the torch to perform welding on thin or delicate materials.

Depositing welded metal in very small lumps may be required.

Additional-processes do not involve melting of the base materials.

These are variously called Brazing, or Soldering depending on an arbitrary but accepted limits of process temperature.

A different process, called Braze Welding is described.

One should know the relative advantages of each of these Additional processes, as explained in the above pages, to decide which one may be preferred to welding in certain cases.

Severing metal may be needed to accomplish a welding job.

Equipment and techniques are derived from accepted welding techniques.

Therefore these operations are included in the Additional-processes in the basic versions available.

Flame-, arc-, plasma- and laser-cutting are all described in our page on Cutting metals.

The deposition of a certain metal, alloy or compound upon a different substrate may give to the treated surfaces special qualities previously not available.

Additional-processes like Hardfacing and Thermal-spray are designed to provide the application of different materials.

Selection of suitable metals, ceramics or composites, and their correct deposition according to specific requirements, provides added value.

Deposits may solve difficult problems of resistance and durability in demanding service environments.

Adhesive Bonding may seem too remote from welding.

It has to be included in the Additional-processes though, as it is still a joining method.

It must be taken into account when all others are not applicable for some reason.

As remarked above, the purpose of this presentation is to introduce some Additional-processes related to welding that are discussed in more detail in the linked pages.

Their importance can be assessed by estimating the cost of implementing them in a complete operation.
