Welding Processes
Welding process is selected from the engineering drawing based on material, thickness, joint configuration, weld symbols and access.
TIG Welding
Thin-gauge stainless steel and aluminum parts where weld appearance and controlled heat input are important.
MIG Welding
Carbon steel, stainless steel and aluminum assemblies where welding speed and consistent welds are required.
Spot Welding
Overlapping sheet metal, enclosures and internal brackets where electrode access allows resistance welding.

Materials for Sheet Metal Welding
We work with a range of metal sheet materials for custom welded parts and assemblies. Common materials include carbon steel, stainless steel and aluminum, with other alloys reviewed according to the drawing, material grade, thickness and welding requirements.
- Carbon Steel---Cold-rolled and hot-rolled carbon steel for frames, brackets, enclosures, housings and fabricated assemblies.
- Stainless Steel---304 and 316 stainless steel for enclosures, panels, housings and welded components requiring corrosion resistance.
- Aluminum---Aluminum sheet for lightweight enclosures, housings, frames and other fabricated assemblies.
- Other Materials---Galvanized steel and other weldable alloys can be reviewed based on material condition, thickness, joint configuration and project requirements.
Our Service
Sheet Metal Assembly
After welding, parts can be supplied as welded subassemblies or further assembled with hardware and mechanical components according to the engineering drawing and BOM.
Hardware Installation
PEM and other self-clinching fasteners, rivets, hinges, latches, handles and other specified hardware can be installed as required.
Mechanical Assembly
Screws, bolts and other mechanical components can be installed according to the drawing, BOM and specified torque requirements. Subassemblies can be fitted and assembled according to the required configuration.
Delivery can be supplied as a welded assembly, a partially assembled subassembly, or a complete mechanical assembly with specified hardware installed.
Our Service
Welding & Assembly Quality Control
We manufacture welded assemblies to the engineering drawing, following specified weld symbols, dimensions, tolerances and assembly requirements. Fixtures are used where needed to maintain part position and alignment during welding, while welding sequence and heat input are controlled to limit distortion.
Before delivery, critical dimensions, hole positions, weld locations and mating interfaces are checked against the drawing. Hardware and assembled components are verified against the BOM where applicable, with any additional inspection requirements reviewed before production.
Our Service
Sheet Metal Fabrication & Assembly Process
Laser Cutting → Forming → Welding → Assembly → Finishing → Inspection
Welding and assembly continue from the sheet metal fabrication process, with parts transferred from laser cutting and forming according to the same engineering drawing and BOM.
Part dimensions, weld locations, hardware and assembly requirements are followed through the welding and assembly stages. Finished assemblies proceed to the specified surface finish and final inspection according to the drawing and project requirements.
Our Service
Post-Weld Finishing
Welded parts and assemblies are finished according to the engineering drawing and project requirements. Weld areas can be ground and blended where specified, while edges and surfaces are prepared for the required finish.
Available finishing options include:
- Weld grinding and blending
- Deburring
- Powder coating
- Wet painting
- Anodizing for aluminum
- Plating
Hardware installation is coordinated with the finishing process. PEM fasteners, hinges and other fittings are installed before or after finishing according to the drawing, coating requirements and final assembly requirements.

FAQ
Welding & Assembly FAQ
Answers to common questions about welding processes, sheet metal assemblies, hardware installation and finishing requirements.
Yes. TIG, MIG and spot welding are available for sheet metal assemblies, with the process selected according to the material, thickness, joint configuration, weld requirements and access shown on the drawing.
Yes, where the joint configuration and electrode access are suitable for resistance welding. Enclosure laps, overlapping sheet and internal brackets are typical applications.
Yes. Aluminum and stainless steel can be welded according to the specified material grade, thickness and joint requirements. These details should be included with the drawing or RFQ.
Yes. PEM fasteners, hinges, latches, rivets and other specified hardware can be installed according to the drawing or BOM. Installation can be coordinated with the required finishing sequence.
Yes. Welded assemblies can be prepared for powder coating, wet painting and other specified finishes. If welds require grinding or blending, or if certain faces are cosmetic surfaces, these requirements should be identified on the drawing or RFQ.
