Choose a handheld laser welder through trials on your material, joint geometry and fit-up, with agreed weld inspection. Fix the exact source, head, cooling, filler and gas scope. Confirm the laser classification and a competent site safety review before installation.
When this equipment fits your project
Evaluate handheld laser welding for accessible fabrication joints where repeatable fit-up and a controlled working area are achievable. Start with drawings, production samples and the required inspection method. If access, gap variation or joint performance remains uncertain, a sample weld is more useful than a power-only comparison. Ask the supplier to identify processes or joints outside the proposed package scope.

Specify the complete configuration
| Decision | Include in your request | Evidence to compare |
|---|---|---|
| Joint result | Alloy, coating, thickness, weld position and gap | Trial report against your inspection criteria |
| Laser package | Exact source, head, power and cooling | Model-specific datasheet and included components |
| Wire and gas | Filler alloy, diameters, feeder and gas supply | Written consumable and utility requirements |
| Production duty | Weld length, batch size and cooling conditions | Complete job trial including setup and stops |
| Work area | Laser class, access, fumes and fire conditions | Documented controls reviewed by competent personnel |
The SENFENG HW technical table lists 1.5, 2 and 3 kW water-cooled variants. Obtain the sheet for the exact offered model because page sections describe different ranges. OSHA laser hazard guidance describes direct and reflected Class 4 hazards; verify the actual machine class and site controls.
Compare installed cost and support
Price the source, welding head, cooler, feeder, gas arrangement, consumables and training separately. Include suitable work-area protection, extraction, commissioning and inspection costs in the project budget. Compare lens and nozzle availability, service response and source warranty exclusions. A low machine price does not define the cost of an accepted weld or a usable installation.
Keep the delivery term, currency, quote validity and included scope consistent. Use the complete project budget tool to organize assumptions, then replace estimates with dated quotations and destination-specific charges. Discuss supplier checks through our sourcing process.
Agree an acceptance test before ordering
Agree sample identity, joint preparation, filler and gas settings before the trial. Inspect the agreed finish and dimensions, then use the specified destructive or non-destructive tests where required by the application. Record rejected joints, preparation and rework time. Review enclosure or barriers, interlocks, access, wavelength-appropriate protective equipment, ventilation and fire measures as a complete installation.
What to include in your RFQ
- Material grades, surface/coating condition and thickness distribution
- Joint drawings, weld types, fit-up gaps, access and weld positions
- Acceptance criteria: dimensions, finish, penetration and required joint testing
- Expected weld length, batch size, duty pattern and operator workflow
- Trial samples and agreed test/inspection method
- Exact laser source, power, head, cooling configuration and duty limitations
- Filler alloy, wire sizes, feeding arrangement and shielding-gas supply
- Supply voltage, phase, frequency and available cooling/utilities
- Work-area layout, laser classification and proposed protection/ventilation measures
- Destination, training, service, consumable availability and purchase timing
Need OEM / ODM customization?
Submit branding, packaging, configuration or engineering requirements for this equipment. Include the target market, initial and annual quantities, required changes and acceptance criteria.
Customization feasibility, permitted branding, development responsibilities, minimum quantity, cost and lead time are reviewed for the proposed supplier and configuration before a quotation is confirmed.
Frequently asked questions
How do I choose between 1.5 kW, 2 kW and 3 kW handheld laser welders?
Choose through representative joint trials rather than a generic power chart. Material, gap, weld position, cooling and required penetration all matter. Compare accepted joints and complete cycle time on the exact proposed configurations.
Can a maximum sheet-thickness claim prove that my joint will meet its requirements?
No. A thickness figure does not prove penetration, strength, leak tightness or finish on your joint. State the acceptance standard or agreed inspection criteria, then test production-like samples and retain the results.
Which material, joint and filler samples should be used for a weld trial?
Use your actual alloy, surface condition, thickness range and typical gap. Include the most difficult joint access and weld position. Match filler and gas to the trial plan, and agree how the weld will be inspected.
What shielding-gas and cooling information should a quotation include?
Ask for gas type, supply requirements, connection scope, cooler specification, ambient operating limits and maintenance requirements for the offered model. Confirm which cylinders, regulators, hoses, coolant and installation work are excluded.
What site protections and training are needed for the proposed laser class?
Confirm the product classification and have competent personnel review the complete work area. Direct/reflected exposure, access, interlocks, protective equipment, fumes and fire precautions all require consideration. Glasses alone do not establish a suitable installation.
How should I compare consumables, source service and warranty exclusions?
Compare dated spare-part prices and availability for optics, nozzles, feeder parts and other wear items. Identify source service arrangements, response times, warranty limits and who pays for transport, labor and diagnosis.
