Metal Door and Door Frame Welders
Resistance Welders for Steel and Hollow Metal Door Manufacturing
Steel door and steel frame resistance welders from Weld Systems Integrators.
Weld Systems Integrators (WSI) designs and manufactures standard and custom resistance welders for both interior and exterior steel doors, hollow metal doors, and door frames. WSI metal door welders are engineered for manufacturers producing everything from 20 to 2,000+ doors and frames per day, with equipment available for hinge reinforcements, stiffeners, end channels, lock boxes, strikes, anchors, pressure plates, and other door and frame components. Our steel door and frame welders create strong, reliable bonds that DO NOT separate under stress and prohibit light and air from penetrating the edges.
WSI’s highly skilled in-house engineering team can tailor or custom design a machine or process for your application. In addition to NEW standard and custom resistance welders, we also provide replacement parts, repair and rebuild services, upgrades, and preventive maintenance for LORS Machinery and other hollow metal door welder manufacturers.
WSI metal door and frame welders are engineered for increased production speed, repeatable weld quality, reduced material handling, and reliable operation. Standard and custom systems are MADE IN THE USA at our Warrensville Heights, Ohio, facility. Give us a call at 844-WSI-WELD or 216-475-5629 for available inventory or to discuss your unique metal door or door frame welder solution.
VIDEO: Door Edge Seam Welder - Model 826VIDEO: Hinge Reinforcement Welder - Model 145
The WSI Model 826 is a GMAW Seam Welder capable of over 60 IPM on lock seam and center/butt seam doors made of steel, galvanized, galvannealed, and stainless steel. This seam welder welds longitudinal seams – butt seams, overlap seams, and lock-joints – on the door edge and automatically detects hinges, door length, and strike plates for reduced set-up.
WSI model 145 is a horizontal dual-gun projection hinge reinforcement welder, rated at 120 kVA. Designed for projection welding hinge reinforcements to steel doors and frames. Horizontal design permits welding with the door in the flat position, eliminating the need to stand the door on the edge and reducing handling. Dual weld guns are operated either individually in a gun-sequence mode or together to permit welding both tabs at a single hinge reinforcement location. Provided pneumatic hold-down pads maintain the door’s flatness during welding.
WSI Metal Door and Door Frame Welder Frequently Asked Questions
What is a metal door welder?
A metal door welder is a resistance welding machine or automated welding system used to join reinforcements, stiffeners, channels, lock boxes, strike components, and other parts to hollow metal doors and frames. Depending on the application, door manufacturing may use spot welding, projection welding, seam welding, or GMAW welding.
What types of welders are available for metal doors?
Door welders from Weld Systems Integrators:
Hinge Reinforcement Welders
- Horizontal dual gun projection welder, 120 kVA rated. Designed for projection welding hinge reinforcements to doors. Horizontal design permits welding with door in the flat position eliminating need to stand door on edge and reduces handling.

Stiffener Welders
- Multi-Spot Welder with ten (10) guns, two (2) transformers rated 70 kVA. Includes a 62” wide pass-thru portal for welding two, three, or four hat-type reinforcing stiffeners onto a door panel.
- Multi-Spot Stiffener Welder featuring twenty (20) guns and five (5) welding transformers rated 120 kVA. Designed for welding hat section stiffeners onto doors up to 8 ft. long.
- Multiple-Spot Welder with twenty-eight (28) weld guns and seven (7) transformers rated 150 kVA. Designed to weld 16 gauge hat section stiffeners to door skin (up to 10 ft. long).
End Channel Welder
- End Channel Welder featuring a single transformer rated 70 kVA and six (6) reciprocating-type weld guns on 4” centers that reach inside the end channel. This welder is capable of welding end channels on both narrow and wide doors.

What types of welders are available for metal door frames?
Metal door frame welders from Weld Systems Integrators:
End Channel Welders
- End Channel Welder featuring five (5) transformers and nine (9) reciprocating type weld guns, 70 kVA rated.
Hinge Reinforcement Welders
- Dual Gun Projection Welder, 120 kVA rated. Designed for projection welding hinge reinforcements to jambs, one hinge per sequence. Dual gun design assures correct weld force on both ends of hinge reinforcement and eliminates weld force distribution problems common to single gun projection welders.
- A Four (4) Station, Eight (8) Head Hinge Reinforcement Welder, permits welding four hinges per sequence. Features eight (8) weld guns and four (4) transformers, 120 kVA rated.

Pressure Plate Welders
- Dual Station Welder, 85 kVA rated. Station one (1) is for welding pressure plate to jamb single hit projection weld. Station two (2) is for welding gussets to the end of the jamb with dual equalizing guns.
Stud & Floor Anchor Welders
- Dual Gun Projection Welder, 85 kVA rated. This welder is designed for welding stud and floor anchors to door frames. Features two adjustable retraction stroke ram-type weld guns and replaceable weld dies.
Anchor & Plumb Bracket Welders
- Single Gun Retraction Projection Welder, 85 kVA rated. This welder is designed to weld anchor and plumb brackets.
How do I choose the right door or frame welder?
Choosing the right door or frame welder depends on the component being welded, door or frame design, material and thickness, required weld locations, production volume, available floor space, and desired level of automation. Low-volume manufacturers may require a dedicated single-purpose welder, while higher-volume operations can benefit from multi-gun or automated welding systems that complete multiple welds during each production cycle.
WSI can evaluate your parts, weld requirements, production rate, and manufacturing process to recommend or custom-design the appropriate welding system.
Can WSI build a custom door or frame welder?
Yes. Weld Systems Integrators designs and manufactures custom resistance welding machines and automated welding systems for hollow metal door and frame applications. Equipment can be engineered around the component, material, production rate, weld requirements, and manufacturing process.
Can WSI replace or rebuild older LORS door welding equipment?
WSI provides replacement parts, repairs, rebuilds, upgrades, and preventive maintenance for LORS Machinery and other hollow metal door welding equipment. This is already a differentiator mentioned on the page and deserves much more visibility.
