Complete Product Offering Reliable, Simple to Operate All Weldable Materials Many Custom Options No Part Size Limitation For All Arc Welding Processes > LWX-72Ultra-Precision Seam Welder Longitudinal seam welding is a process used to produce linear welds on a wide variety of parts. For many industrial applications it is necessary to form the material into a desired shape, e.g. a cylinder or rectangular tube, and then weld the abutting edges to form a rigid structure.The traditional method of doing this is to manually hold the edges in alignment, tack weld them and then complete the linear weld. This is done manually or by use of a simple carriage carrying the welding torch. This type of procedure is costly and time consuming for the following reasons: Holding the edges accurately in alignment is diffi cult for the full length of the part.Օ Tack welding takes time and leads to local defects in the area of the tack weld. There is little effective chilling of the weld joint area leading to distortion and oxidation of the weld and surrounding area.Օ Maintaining the dimensional accuracy of the part is diffi cult.Jetline longitudinal seam welders provide a solu-tion to these problems. They are designed for the straight line welding of all weldable materials in thicknesses varying from 0.005" (0.1 mm) to 3/8" (10 mm), thicker materials can be accommodated using Jetline's unique mandrel adjustment capa- bility. They optimize the welding process, reduce welding costs and improve the quality of the weld. All Jetline seam welders use "chill-shunt" tooling which absorbs and dissipates heat through the use of additional mass operating under pressure against the work piece in the weld zone.The longitudinal seam welder clamps the materi-als to be welded fi rmly in alignment giving uniform chill to the weld. It also provides the facility to move the welding equipment accurately along the weld seam. This produces a butt weld free of melt-through, burnbacks, extreme shrinkage or distortion.Jetline longitudinal seam welders feature the ulti-mate in ease-of-operation and accuracy. Modern, simplifi ed controls reduce operator fatigue. The shallow clamping structure design increases visibility and effi ciency.Jetline manufactures a standard range of seam welders for part lengths up to 240" (6 m), longer lengths are available on special order. The range includes the following models: External Style Internal Style Combination Style Elevating Style Bench StyleJetline has manufactured seam welders for almost 50 years and offers the widest range available from any manufacturer.

Unique side beam track uses case hardened roundways for smooth, precise carriage travel. Linear accuracy is within +0.005" (0.1 mm) on the precision model and +0.015" (0.3 mm) on the standard model.The travel carriage rides on the track using hardened bearings. The 9627 microprocessor controller provides precision speed control. Various speed ranges are available, standard speed holding accuracy is +2% of the rated speed, with a tach-generator this is improved to better than +1%. A precision model provides +0.1% speed holding accuracy.Various types of alignment gages are available for the...

Note: Addition of a tach-generator to the standard carriage motor improves the speed holding accuracy to +1% of the rated speed. >

Pressure Hold-down Clamping pressure is adjustable up to 5,000 lb/ft (75 kg/cm). Safety Switch The safety switch is activated when the mandrel latch is closed. It protects the mandrel by preventing clamping when the latch is disengaged. Mandrel Tooling Adjustment All Jetline seam welders incorporate a 2" (50 mm) back-up tooling adjustment. This is effected by lifting or lowering the whole mandrel and provides the abil- ity to accommodate thicker back-up inserts or to adjust for the welding of different parts. Continuous Hold-down Strips All precision seam welders feature these strips which...

MIG Welding Seam Welder Welding Gear Auto-Loading Seam Welder Jetline produces a seam welder model designed specifi cally for use with the GMAW (MIG) welding process. The unit is supplied complete with weld gear and is available on short delivery in 4, 6 and 10 ft models. In addition to the extensive range of longitudinal seam welders shown in this brochure, Jetline manufactures the type illustrated above. This is a variation of a standard external seam welder with additional features to automate the loading, aligning, clamping and welding of the parts. Special air-operated blades mounted...
