Miller Introduces Submerged Arc Accessories

Posted by Michelle Howard

Miller Electric Mfg. Co., a manufacturer of arc welding equipment, has announced two new accessories for submerged arc welding (SAW) systems. The new Three-Wheeled Tractor provides a smaller size for improved flexibility in subarc welding applications, while the new 30-90 mm External Cladding Head optimizes feeding of cladding strip for improved weld quality in SAW and electroslag cladding applications.

The Three-Wheeled Tractor can be configured into multiple positions, providing greater flexibility and setup options in SAW applications in industries such as shipbuilding and railcar. It also has a compact size. In addition, the new SubArc Tractor Interface Digital is an all-in-one interface that lets welding operators control the tractor as well as the welding functions from the same panel, for ease of use.

The tractor also has regulated speed control technology, which allows the system to automatically adjust welding travel speeds based on changes in weight, angles or other variables. This helps ensure that travel speeds remain at set parameters - for improved weld quality and productivity.

The new 30-90 mm External Cladding Head has a full-width strip drive roller that includes independent adjustments at three separate points - one for each 30-millimeter increment - compared to only one point of adjustment for other cladding heads on the market. This allows welding operators to adjust pressure in three areas across the cladding strip, to optimize strip feeding and provide trouble-free operation.
The ability to fine-tune the pressure allows welding operators to optimize the external cladding head performance for the specific needs of the application. In addition, individually adjustable spring-loaded contact jaws provide optimal current transfer, reducing the risk of cladding failures. The external cladding head is designed for many submerged arc and electroslag cladding applications, including pressure vessel, pipe, petrochemical and offshore.
