Advertising Signs Welding

Wed, 28 Oct 2026 00:00:00 +0000

Background

The advertising sign industry needs to weld 0.8–1.5mm stainless steel letters, galvanized sheet brackets, and aluminum composite panels. Traditional spot welding produces large, rough welds; TIG welding causes deformation and requires polishing. Laser welding does both spot fixing and continuous sealing with a clean surface.

Door & Window Frame Welding

Wed, 28 Oct 2026 00:00:00 +0000

Background

The door and window industry heavily uses galvanized steel tubes (1.2–2.0mm) and stainless steel tubes for frames and security grilles. Traditional TIG or MIG welding inputs too much heat, causing deformation that leads to poor fit and requires grinding. Laser welding solves this perfectly.

Solution Specs

Item	Details
Machine Model	Zhijie MJ-10-BFL / MJ-15-BFL
Laser Source	1000W / 1500W fiber laser
Wire Feeder	Standard auto wire feeder
Shielding Gas	CO₂ (galvanized) / Argon Ar (stainless)
Welding Material	Galvanized steel tube 1.2 – 2.0mm / stainless steel tube
Welding Type	Fillet joint, T-joint, butt joint

Key Results

Metric	Traditional TIG	Laser	Improvement
Heat Deformation	0.5 – 1.5mm	≤ 0.1mm	No grinding, install directly
Welding Speed	~ 80 mm/s	≥ 250 mm/s	3x faster
Zinc Layer Burn-off	Significant, needs repaint	Minimal, mostly preserved	Less anti-corrosion work
Weld Appearance	Rough, needs grinding	Smooth, no grinding	100% labor saved

Stainless Steel Pipe On-Site Welding

Wed, 28 Oct 2026 00:00:00 +0000

Background

Stainless steel pipe installation (water supply, food-grade, chemical) requires on-site welding. Traditional TIG welding is slow, highly dependent on operator skill, and prone to porosity when ventilation is poor. The handheld laser welder is portable, and with a wobble head attachment, delivers single-pass full penetration.

Solution Specs

Item	Details
Machine Model	Zhijie MJ-15-BFL handheld laser welder
Laser Source	1500W fiber laser
Welding Head	Standard + optional Wobble Head
Wire Feeder	Standard auto wire feeder
Shielding Gas	Argon Ar (backside needs argon purge)
Welding Material	Stainless steel tube 304 / 316, 1.5 – 3.0mm
Fiber Length	10m (standard), optional 15m / 20m

Key Results

Metric	Traditional TIG	Laser (wobble head)	Improvement
1.5mm Pipe Speed	~ 80 mm/min	≥ 250 mm/min	3x faster
3.0mm Pipe Penetration	Needs 2 passes	Single pass full penetration	2x faster
Porosity Risk	High in poor ventilation	Extremely low (stable beam)	99%+ UT pass rate
Portability	Heavy welder + gas bottles	12kg handheld, 10m fiber	Fits in tight spaces

Key Advantages

Portable — handheld gun only 12kg, 10m fiber reaches any on-site location
220V power — works from a standard outlet, no 380V power needed
Wobble head — beam oscillation widens the molten pool for single-pass 3mm pipe joints

Auto parts welding

Tue, 27 Oct 2026 00:00:00 +0000

Background

The automotive industry demands extremely high weld strength and flawless appearance. Traditional TIG welding on thin sheet metal suffers from large heat input, workpiece deformation, and low efficiency — leading to high rejection rates and costly rework.

Solution Specs

Item	Details
Machine Model	Zhijie MJ-15-BFL handheld laser welder
Laser Source	1500W Keplin / Guangfang / Raycus fiber laser
Wire Feeder	Standard auto wire feeder
Shielding Gas	Argon Ar
Welding Material	Galvanized steel 1.0 – 1.5mm
Welding Type	Continuous lap weld on exhaust pipe flanges

Key Results

Metric	Before (TIG)	After (Laser)	Improvement
Weld Width	~ 3.5 mm	≤ 1.2 mm	2.9x narrower
Welding Speed	~ 10 mm/s	≥ 30 mm/s	3x faster
Rework Rate	~ 8%	~ 0.5%	16x lower
Post-weld Polishing	Required	Eliminated	100% labor saved
Heat Affected Zone	Large	Very small	No workpiece deformation

Customer Testimonial

“We replaced three TIG welding stations with one Zhijie 1500W laser welder. Output per shift nearly tripled. The laser welds are so clean we completely removed the polishing step. ROI was under 6 months.”

— Production Manager, Chinese auto parts supplier

Hardware & Kitchenware Welding

Tue, 27 Oct 2026 00:00:00 +0000

Background

Hardware and kitchenware factories mass-produce stainless steel pots, sinks, hooks, brackets, and more. Traditional welding requires extensive post-weld polishing — time-consuming, inconsistent in quality, and costly.

Solution Specs

Item	Details
Machine Model	Zhijie MJ-15-BFL handheld laser welder
Laser Source	1500W fiber laser
Wire Feeder	Standard auto wire feeder
Shielding Gas	Argon Ar
Welding Material	Stainless steel 304 / 201, 1.0 – 2.0mm
Welding Type	Sink lap weld + fillet weld

Key Results

Metric	Before	After	Improvement
Weld + Polish Time	~ 25 min / unit	~ 8 min / unit	3x faster
Labor Cost	2 workers (welder + polisher)	1 worker, no polishing	50% labor saved
Weld Appearance	Inconsistent	Uniformly smooth, machine-controlled	Perfect consistency
Daily Output	~ 80 units	~ 240 units	3x throughput

New Energy Battery Tray Welding

Tue, 27 Oct 2026 00:00:00 +0000

Background

EV battery trays require welding 1.0–3.0mm aluminum alloys (6061, 5052). Aluminum has high reflectivity and excellent thermal conductivity — traditional welding suffers from poor fusion, heavy spatter, and severe deformation. Laser welding solves all three.

Laser Power	1500W / 2000W
Shielding Gas	Nitrogen N₂
Welding Material	Aluminum alloy 6061 / 5052, 1.0 – 3.0mm

Tensile Strength	≥ 70% of base metal
Deformation	Minimal, no post-weld straightening needed
Consistency	Stable mass production

Pressure Vessel Welding

Tue, 27 Oct 2026 00:00:00 +0000

Background

Pressure vessel manufacturing requires high-strength, porosity-free welds that strictly meet GB/T 150, ASME VIII, and other standards. Traditional multi-pass TIG/MIG welding on 3–5mm steel plate needs 3–4 passes — slow, prone to inter-pass slag inclusions, and high rework rate.

Solution Specs

Item	Details
Machine Model	Zhijie MJ-20-BFL handheld laser welder
Laser Source	2000W fiber laser
Wire Feeder	Auto wire feeder (standard)
Shielding Gas	CO₂
Welding Material	Carbon steel Q355, 3.0 – 5.0mm

Porosity Rate	~ 3% (inter-pass slag)	~ 0.2%	15x lower
UT Test Result	Meets GB/T 150	Meets GB/T 150	Same quality, double speed
Heat Input	High, pre-heat needed	Low, no pre-heat	Simplified process
