When you specify Triten Bulkwelding, you're getting the one-and-only "original"
During the 1950's, our company was in the business of manufacturing abrasion resistant piping and in rebuilding slide valves. The valve technology of the times was placing extreme demands on the working parts, especially those used in the petroleum refining industry. High temperature solid catalyst was moving at greater and greater velocities, causing abrasion damage to hydrocarbon processing units.

We believed there was an opportunity to improve the welded hardfacing that was used to resurface these units. The old hardfacing was expensive, time-consuming to apply, and wearing out more quickly than desired. This led to an extensive R&D effort spearheaded by founder, Roman F. Arnoldy The end result was a totally new and original, patented process for hardfacing named Bulkwelding, introduced in 1961.

It was cost-efficient, extremely hard, and longer wearing. Even today, we continue to lead in Bulkwelding applications, with over 14 U.S. and foreign patents or patents pending on processes, equipment and products that utilize this technology.

	The advantages of Bulkwelding brought a reputation for innovation to our firm, the Texas Alloy Products Company (TAPCO). This unique process now made it possible for us to produce hardfaced plate, pipe and fabricated systems in quantity. Demand for these products was high, and that led us to establish a brand new division in 1975, Overlay Product Systems (OPS).

Currently, both OPS and TAPCO operate under the Triten Corporation banner. And our position as a supplier of overlays has not changed, over the years. We are still the innovator, the leader, and provide the industry standard by which all overlays are measured.

How Bulkwelding produces a wear-resistance second to none.
We pioneered the overlay process known as Bulkwelding. Today it remains the most resistant cladding commercially available for abrasion and impact problems, and produces the highest abrasion resistance per dollar of expense for virtually any application.

The process capitalizes upon the addition of a controlled amount of Bulkwelding powder—composed of metal alloys—to an automatic welding system.
 

In the Bulkwelding diagram, you can see that there is a base metal of carbon steel, and that the overlay is welded to the base. The welding mechanism feeds a granulated Bulkweld powder to the work piece just ahead of the welding electrode. The particular chemistry of the resulting weld is governed by which types of alloys are used in the Bulkweld powder, and by how they combine with the electrode, as well as with the diluted base material.

In addition to laying down a highly wear-resistant cladding, there are many advantages to the Bulkwelding process, itself.

Bulkwelding substantially increases the deposition rates of weld metal over those obtainable with normal single wire operation, but with no increase in welding current, dilution or heat input. This enables us to provide a more competitively-priced product to our customers.

Another economy stems from there being less distortion in Bulkwelding, because of lower heat input. So there is less re-working of the piece, after Bulkwelding.

And, where ordinary submerged arc welding produces large carbides in the microstructure, in Bulkwelding, the carbides are smaller and finer, allowing them to be more densely packed. Ultimately, this particular quality gives a Bulkwelded product its extremely high abrasion resistance.
