MIG Welding – Box Plate Girders – Jamestown, Portarlington County Laois


The Latest Technology for Precision Welding 

At our site in Portarlington, County Laois Jamestown Manufacturing Ltd. use a range of modern welding technologies to produce welded box plate girders of the highest quality.

The Weldycar

For this project, box girders were fabricated using the Weldycar. This is a torch carriage which has its own driving wheels, and is designed for mechanising semi-automatic welding. It travels the length of the girder producing a single continuous weld, which means that no feathering is required. It will work over eight-hour period welding 260 millimetres (8-millimetre fillet weld) per minute, and without stopping and starting along the way. This is much faster than a human welder, who could be expected to achieve around 150 millimetres per minute with stops every 500 to 800 millimetres; in addition, the Weldycar produces a clean, uniform, and consistent weld. This project, which also used some manual metal inert gas (MIG) welding, was completed within its planned five-day time scale.

Submerged Arc Tractor

Jamestown are also able to call on their submerged arc tractor equipment when fully automatic welding is required. In this process, an automated welding head produces an arc which is submerged by a layer granular fusible flux, which protects it from the atmosphere and also reduces weld spatter. This is a fast process particularly suited for long straight welds such as the fabrication of cellular beams.

Kranendonk Robotic Welding

Our Kranendonk robotic welding equipment uses smart sensors to deal with changing designs, so can be programmed to deal with non-repetitive production; the software can generate its own robot paths, creating a truly futuristic production process.

Other Welding Options

Jamestown aims to find the most efficient welding solution for every project. There are some applications where computerised processes cannot provide the answer. In these circumstances, nothing beats a skilled welder with the right equipment, such as our metal active gas (MAG) welding tools, for versatility and swift turnaround.
