Let's get started

Why Multipass Welding Has Traditionally Been Difficult

Traditional robotic multipass programming typically involves:

  • Teaching each pass separately and manually calculating offsets

  • Creating disconnected programs that are hard to coordinate

  • No way to test individual passes before running complete sequences

  • Complex editing that often requires starting over

Beacon changes this by organizing everything into a clear workflow while keeping your welding expertise central to every decision.

With Beacon, Your Welding Process Stays the Same

You’re still making all the same welding decisions:

  • Root pass parameters and technique

  • Where each subsequent pass should be positioned

  • Cooling times and heat management strategies

  • Weld parameters for each pass

Beacon just gives you better tools to implement those decisions without the manual calculations and program juggling.

What is Multipass Welding?

Multipass welding is a welding technique which involves depositing multiple layers (passes) of weld metal to build up a stronger, thicker weld. It is used when a single weld pass is not sufficient to fill a joint or achieve the required weld strength, especially in thick materials or high-stress applications.

With Beacon, leveraging multipass welding becomes a remarkably flexible and powerful process. Beacon's intuitive tools simplify the setup of complex multipass procedures while providing granular control over each pass, empowering you to achieve high-quality, robust welds efficiently.

Multipass Welding with Beacon: The Benefits

Faster Programming for Complex Welds: Significantly reduce programming time for multipass jobs. Beacon's interface makes it easy to teach the root pass, add fill, cap passes, and individually customize weld settings for each.

Full Edibility and Granular Control: Retain complete flexibility even after converting to a multipass sequence. You can still individually edit the position and weld settings for any point within any pass. Plus, easily use the "Start Here" feature on any specific point in the multipass sequence to begin program execution exactly where you need.

Better Heat Management: Achieve better heat management across multiple passes by adding interpass cooling actions or alternating weld directions between layers, all within the Beacon interface.

Improved Consistency: Ensure consistent multipass welds from part to part, with the precision and repeatability you've come to expect from your Hirebotics cobot.

What Makes Beacon Multipass Different:

  • No Guesswork: Execute individual passes to verify before continuing

  • Real-World Positioning: Guided Teach uses actual robot positions, not theoretical calculations

  • Reference Previous Work: Move To buttons help position each pass based on completed ones

  • Same Steps, Better Tools: We don't change what you do — just make it way easier


Getting Started: How to Use Multipass Welding in Beacon

Teach Your Root Pass

First, program the initial weld path as you normally would by adding weld items in Beacon. This path will serve as the root pass for your multipass weld.

Ensure the root pass weld settings and torch angles are accurate.

Access the Multipass Feature

Click the three horizontal dots (...) next to the weld item you want to convert (this must be the first item of a weld path):

Access the Multipass Feature

Access the multipass feature

From the dropdown menu, click "Convert to Multipass".

Convert to Multipass

Convert to multipass

A "Multipass Settings" window will show up:

Multipass settings window

Configure the Multipass Weld

Enter the required Additional Passes (excluding the root pass).

Select the end weld sequence. This is the last weld that will be included in the multipass. By default, it ends on the same weld that is selected.

Select the end weld sequence

Select the Travel/Work Angle Mode

  • Relative Mode: Choose this if you want the travel and work angle values for subsequent passes to be offsets applied to the root pass angles (e.g., Root pass work angle is 45°, relative setting is +5°, subsequent pass will be 50°).

  • Fixed Mode: Choose this to set specific, absolute travel and work angles for subsequent passes, which will override the root pass angles for those passes.

    Select the Travel/Work Angle Mode

The Guided Teach Verification Cycle

This is where Beacon eliminates the guesswork from multipass programming.

Teaching the Pass Offsets

Beacon offers a Table-based approach to enter the path offset values for subsequent passes as well as a Guided Teach option (recommended for ease).

Why Guided Teach Works Better: Instead of manual calculations, you show the robot exactly where each pass should go and verify it works before continuing.

Offset Info

For a detailed explanation of what each offset setting means and how it affects the torch path, please click the Info button.

Guided Teach Method (Recommended for ease)

The Verification Process:

  1. Teach Pass Position: Move robot to desired starting point for the pass

  2. Execute Pass: Test the individual pass to verify motion and welding

  3. Evaluate Results: Use the actual weld results to inform next pass positioning

  4. Reference Previous Work: Use Move To buttons to see where completed passes started/ended

  5. Repeat: Build each subsequent pass based on real feedback

Detailed Steps:

Use the Teach button on any pass to enter Guided Teach.

Teach button

When teaching the multipass, you can use the Teach Offsets button to freedrive the robot to the correct location or modify the offsets manually.

Note: Rotary welds only support manual entry currently.

Teach offsets

After clicking the Teach Offsets button, move the torch to the desired location and press the blue button on the the puck to save the offsets.

Click Cancel to stop teaching:

Pro Tip – Move To Reference Points: You may use the Move To button to move the robot to the previous passes' start and end points if you need to reference them. This makes positioning much more intuitive than trying to calculate offsets manually.

Use Move To for intuitive positioning

After capturing the point, the offsets will be populated and you will have an option to Execute Pass.

Execute Pass button

Why This Matters – Execute Pass Verification Executing the pass will run a one time weld using the offsets you just taught. This is key to eliminating guesswork - test each individual pass to verify motion and welding before continuing to the next. No more hoping your calculations are right.

Pass Navigation: Use the navigation buttons at the bottom to switch between passes.

Pass Navigation buttons switch between passes

Click Done or the close icon in the top left to exit Guided Teaching.

Assign Weld Settings for Each Pass

You can select custom Weld Libraries (pre-saved settings) for each individual pass.

Select a Custom Library under Weld Library

If no specific weld library is selected for a subsequent pass, Beacon will default to using the root pass weld settings for that pass.

Your Control: You make all parameter decisions - current, voltage, travel speed. Beacon just organizes them clearly for each pass.


Comprehensive Post Actions for Heat Management

Post actions are non-weld points that can be added to the end of each pass. These give you complete control over heat management and positioning between passes.

Add Post Actions (Optional)

Improve heat management or automate steps between passes by adding Post Actions.

Available Post Actions:

  • Wait For (time) - Allow specific cooling time

  • Wait For (operator) - Pause for operator inspections or part checks

  • Air Move - Move without torch contact to retract, reposition, or clear obstacles

  • Move to Home - Return to home position

Advanced Sequencing Examples:

  • Pass 1 → Wait For (3 minutes) → Move to cleaning station

  • Pass 2 → Wait For (operator inspection) → Air Move to next position

  • Pass 3 → Move to Home → Wait For (5 minutes)

Setup Steps:
