Automated Welding with DOBOT

Consistent seam quality, higher productivity, and safe human-robot collaboration — in a complete cobot + welding software package.

Overview

Why automate
your welding?

Finding skilled welders is becoming harder and more expensive. At the same time, manual welding exposes staff to arc flash, fumes, and heat — leading to variable seam quality and increased rework.

DOBOT cobots offer a complete solution: high repeatability, uniform seams, 24/7 operation, and safe collaboration alongside your welders — without complex production cells.

  • Sawtooth, spiral, trapezoid, sine, crescent, and triangle weaving patterns
  • Touch sensing & Through-Arc Seam Tracking for accuracy in real conditions
  • Compatible with 10+ welder brands (Fronius, OTC, Megmeet, Lorch, Aotai, EWM)
  • Level 5 collision detection — safe collaboration without a cage
  • Plug-and-play setup on a mobile platform or magnetic base

Key Advantages

What makes our solution
different

Plug-and-Play

Blocky programming and ready-made welding templates. From unboxing to the first seam in minutes, with no coding required.

Flexible Mobility

Mobile platforms and magnetic bases let you change workstation or part in seconds.

Smart Sensing

Touch sensing for seam location, TAST and laser tracking to correct thermal distortion on the fly.

Safe Collaboration

Level 5 collision detection and certified safety — no mandatory cage in most applications.

Workflow

From idle cobot to
production seam in 3 steps

The welding software guides the operator step by step. No programming knowledge required.

Select Welder
Step 01

Select Welder

Pick your welder manufacturer from a ready list of 10+ brands. The system automatically loads the correct communication protocol.

Configure Parameters
Step 02

Configure Parameters

Adjust current, speed, weaving, and multi-pass from a parameterized interface. Save profiles for recurring products.

Visual Programming
Step 03

Visual Programming

Build the path with drag-and-drop blocks. No programming — your operator builds the program in minutes.

Weaving Patterns

Six weaving patterns
for every type of seam

From thin sheet-metal seams to multi-layer multi-pass on thick plate — choose the pattern and tune amplitude, frequency, and dwell time.

Hardware Solutions

Two ready stations
for every type of production

Instead of building the cell from scratch, start with a DOBOT pre-engineered welding station and add the extras you need.

DOBOT Mobile Welding Platform with the CR10A cobot and industrial welder
Option 01

Mobile Welding Platform

Complete station with the CR10A on a wheeled base. A threaded platform fits every type of workpiece. Ideal for production with frequent product changes.

DOBOT CR5A cobot with magnetic base for flexible welding
Option 02

Magnetic Base Solution

The CR5A on a magnetic base clamps directly onto the workpiece. Zero setup time, ideal for small-batch and large-format products.

FAQ

Frequently Asked Questions

Which welders do DOBOT cobots work with?
We support all major brands on the market — Fronius, OTC, Megmeet, Lorch, Aotai, EWM, Lincoln, Kemppi, Cloos, SKS, and more. Communication is handled via 4 different protocols (analog, digital I/O, CAN, DeviceNet) depending on the welder model.
Do I need a programmer to use it?
No. DobotStudio Pro uses blocky visual programming — drag and drop ready-made blocks. An experienced welder builds their program in under an hour after basic training. No coding knowledge required.
How accurate is the seam on warped or thermally distorted parts?
The system combines touch sensing for initial seam location and Through-Arc Seam Tracking (TAST) or laser tracking for continuous correction during welding. This compensates for thermal deformation and manufacturing tolerances, maintaining a uniform seam.
What weaving patterns are supported?
Six ready-made motifs: sawtooth, spiral, trapezoid, sine, crescent, and triangle. Each pattern is tunable in amplitude, frequency, and dwell time. Covers fillet welds through multi-layer multi-pass on thick plate.
Do I need a safety enclosure?
In most applications, no. DOBOT cobots feature Level 5 collision detection that stops motion in milliseconds. For welding with strong arc flash we recommend welding curtains for operator protection — but not a full cage.
How long does installation take in my production?
With our mobile-platform or magnetic-base station, initial installation and calibration are completed the same day. Operator training and first production parts follow within 1–2 working days.
