SZGH Welding Robot Arm — Arc, Laser & Collaborative Welding Cobots

SZGH manufactures a complete range of welding robot arms for arc welding, MIG welding, TIG welding, spot welding, and laser welding — plus a full family of collaborative welding cobots that operate safely alongside human welders without a safety fence. Every SZGH welding robot is built in our Shenzhen and Dongguan factories with a self-developed EtherCAT-1KHz controller, ships pre-integrated with wire-feeder interface and welding-torch mount, and carries CE certification plus IATF 16949:2016 automotive quality management compliance. Whether you need a compact 7 kg collaborative welding cobot for a small metal workshop, a 6-axis heavy arc welding robot with 2.1 m reach for structural steel, or a 20 kg laser welding robot for high-mix stainless steel work, this page helps you pick the right model in three minutes — filtered by welding process, payload, reach, and application. Free engineering consultation and 24-hour quote included.

Choose Your Welding Robot by Application

How to Choose the Right Welding Robot

Choosing the right welding robot comes down to six decisions:

1. What welding process do I use — arc (MIG/TIG), spot, or laser?

Arc welding is the most common — use a traditional 6-axis arc welding robot (SZGH H1500/HZ1500/HZ2000/H2100) for continuous 2- or 3-shift production, or a collaborative welding cobot (SZGH-0907/1406/1415/1820) if you want fenceless deployment and mixed human-robot workflow. Choose a laser welding robot (SZGH-1415-L / -1820-L) if you need narrower heat-affected zones, higher travel speeds, or cosmetic joints on stainless steel and thin sheet.

2. What payload does my torch require?

A standard MIG torch with cable pack weighs 3–5 kg — any SZGH welding robot can handle it. Water-cooled TIG torches with dual wire feeders or laser welding heads with cooling can hit 12–15 kg — choose the Master Series (15 kg) or 20 kg models.

3. What is the largest part I need to weld?

Measure the diagonal of your largest weldment. Match it to robot reach: 1,077 mm (SZGH-0907) for benchtop parts, 1,460–1,500 mm for cabinets and kitchenware, 2,000–2,100 mm for full-size structural steel. Consider a ground track for parts over 2 m.

4. Do I need a safety fence, or can I use a cobot?

If floor space is tight, staff work near the cell, or you plan mixed manual + robot welding on the same part, choose a collaborative welding cobot. If the cell runs at max speed 24/7 with no human interaction, a traditional arc welding robot is faster and cheaper per weld.

5. How much does a welding robot cost?

A new SZGH welding robot cell typically prices USD 15,000 – 45,000 including robot, controller, welding torch package, positioner (optional), and safety fencing. Collaborative welding cobots start slightly higher than same-payload arc welding robots but save on fencing and integration.

6. What's the ROI vs a manual welder?

Typical payback: 12–18 months when weekly robot-welding hours exceed 40 hours. Below that, a manual welder may be more cost-effective. SZGH engineers provide a free ROI worksheet — send your part, weekly volume, and current cycle time.

Why Manufacturers Choose SZGH Welding Robots

1. Self-Developed Controller & Welding Software

Every SZGH welding robot ships with the SZGH-developed motion controller and welding-specific software — arc tracking, weaving, multi-layer/multi-pass, wire-start/end optimization, and touch sensing built in. No third-party welding-software license required.

2. IATF 16949:2016 Automotive-Grade Quality

Every model complies with IATF 16949:2016, the global automotive quality management standard — the same standard demanded by Tier-1 automotive Tier suppliers.

3. XI Black-Box Fault Recorder (Industry First)

Every welding fault is logged with timestamp, joint angles, torch current, and wire-feed rate — accelerating warranty claims and predictive maintenance.

4. 10-Level Collision Protection + Power-Off Safety

Innovative power-off protection ensures the robot enters a safe state even if the main cable is cut mid-cycle — a life-safety feature unique to SZGH.

5. Fenceless Cobot Option

SZGH is one of the few Chinese manufacturers offering both traditional welding robots and collaborative welding cobots — you can standardize on one supplier, one controller, one training program across your whole factory.

6. CE + CR + SEMI S2 + NRTL Certified

Full export compliance for EU, China, semiconductor plants, and North America — one set of certifications, all major markets.

Frequently Asked Questions — SZGH Welding Robot

Q1: What is an SZGH welding robot?

An SZGH welding robot is an industrial welding robot arm manufactured by Shenzhen Guanhong Automation. The lineup includes 6-axis traditional arc welding robots (SZGH H-series and HZ-series), collaborative welding cobots in Easy Series (6–7 kg payload) and Master Series (15–20 kg payload), and laser welding robots in the Light Series. All models are CE certified and comply with IATF 16949:2016 automotive quality standards.

Q2: How much does an SZGH welding robot cost?

Pricing depends on model, welding process, and cell integration. A complete SZGH welding robot cell typically prices between USD 15,000 and 45,000, including robot, controller, welding torch package, and optional positioner. Free line-itemized quote available within 24 hours.

Q3: What is the difference between an arc welding robot and a welding cobot?

An arc welding robot is a traditional caged industrial robot built for maximum speed and duty cycle in dedicated welding cells. A welding cobot (collaborative robot) is designed to operate safely alongside human welders without a safety fence, using force-limited joints and drag-and-teach programming. SZGH offers both — traditional models for 24/7 production, cobots for flexible small-batch and mixed manual-robot workflows.

Q4: Can SZGH welding robots do MIG and TIG welding?

Yes. All SZGH welding robots support MIG, TIG, spot, and pulse welding out of the box. Torch mounts, wire-feeder interfaces (Fronius, Panasonic, Lincoln, Miller compatible), and welding process software are pre-integrated. Laser welding is supported on the SZGH-1415-L and SZGH-1820-L Light Series models.

Q5: Are SZGH welding robots CE certified?

Yes. Every SZGH welding robot carries CE certification, plus CR, SEMI S2, and NRTL certifications. Traditional welding robots additionally comply with IATF 16949:2016 automotive quality management standards. Test reports available on request (EN 60204-1, EN ISO 12100, EN ISO 10218-1/2).

Q6: What is the maximum reach of an SZGH welding robot?

Standard reach ranges from 1,077 mm (SZGH-0907-A) up to 2,100 mm (SZGH H2100-B-6). The SZGH H2100-B-6 and SZGH-1820-A/L can be mounted on a ground track for effective reaches of 6 m or more, ideal for large structural steel or agricultural machinery.

Q7: Can I install an SZGH welding cobot without a safety fence?

Yes, in most applications. All SZGH collaborative welding cobots (SZGH-0907/1406/1415/1820) meet ISO/TS 15066 power-and-force-limiting requirements and are CR/CE/SEMI S2/NRTL certified. A risk assessment based on your specific torch, wire feeder, and workpiece is still required — SZGH engineers can help conduct it.

Q8: What is the ROI of an SZGH welding robot vs a manual welder?

Typical payback is 12–18 months when weekly welding hours exceed 40. Beyond throughput gains, robots deliver more consistent weld quality (typical defect rate drops from 4–6 % to under 1.5 %) and eliminate welder fume exposure. Free ROI worksheet available on request.

Q9: Does SZGH offer welding robot installation and training?

Yes. SZGH offers three service tiers: (1) self-install with free video and PDF guides, (2) remote-guided installation with engineer video call, (3) on-site installation and training by SZGH engineers. On-site service is available in USA, Turkey, Russia, Brazil, UK, Thailand, Mexico, Peru, Indonesia, India, Vietnam, Romania, Egypt, Morocco, Moldova, Bangladesh, and Canada.

Q10: What warranty do SZGH welding robots come with?

Standard warranty is 12 months on the robot body and controller. Extended warranties up to 36 months are available. Spare parts ship globally within 48 hours from the SZGH Shenzhen warehouse.
