Metals Robot Orders Rise: BLOK Welding Expansion

AGT BLOK Robotic Welding Systems offer a configurable approach to expanding welding capacity for large steel assemblies without requiring identical cells at every plant. For steel skids, trailer frames and variable-batch frame assemblies, the useful goal is a common machine family with configurations matched to each location’s work.

Metals-sector robot orders grew 18%

Metals-sector robot unit orders in North America increased 18% year over year in the second quarter of 2026, in the Association for Advancing Automation report published August 11, 2026. Metals orders grew 3% across the first half. The broader market recorded 8,940 second-quarter robot orders, up 4.3% year over year; non-automotive buyers accounted for 56% of units.

Quarterly year-over-year comparisons use a consistent reporting cohort, while first-half comparisons use aggregate reported totals. These figures describe industrial robot purchases by sector, not welding-cell output or a welding-only order series.

U.S. industrial robot installations reached almost 38,500 in 2025, up 12%, in the International Federation of Robotics release published September 24, 2026. Those installations cover an earlier year and a narrower geography than the North American order data. Neither measure establishes the welding demand at an individual plant.

Where BLOK adds welding coverage

The AGT BLOK Robotic Welding Systems family uses articulated industrial robots for arc welding large assemblies. External robot travel and application-specific workpiece positioning provide configuration choices for covering skids, trailer frames and large fabricated frames. The useful strength is configurable coverage, not a guarantee that every joint in a weldment is accessible.

BLOK 400 provides external X/Y travel on rails. BLOK 500 adds vertical positioning; its external Z axis is positioning only. Optional gantry rotation is available for both arrangements. Evaluate these choices by the torch approaches they allow within the actual assembly, rather than by workpiece length alone.

Customer-supplied tables or trestles and optional headstock/tailstock positioners represent different support arrangements. Include the proposed supports and fixtures in the reach review so blocked torch approaches and inaccessible joints remain visible in the manual-work estimate.

Standardize the platform, not every cell

For phased expansion, the practical investment approach is to standardize selectively: keep a common machine family where it fits while choosing travel, workpiece positioning and joint detection for each workload. A recurring trailer-frame mix and a varied-skid mix should not be assumed to need the same configuration simply because both involve large steel assemblies.

BLOK’s programming choices include teach-pendant, offline and automatic programming. Cortex automatic programming can use CAD welding information to generate welding paths. For variable batches, confirm the selected software package, supported model exports and required weld definitions before estimating programming labor and changeover time. Review any intended reuse of programs across plants against their actual cell configurations.

If later expansion is part of the business case, have that extension reviewed with the initial configuration. Modular architecture supports configuration choices, but the investment plan still needs a defined expansion path rather than an assumption that every future workload will fit the first installation.

Phase investment around completed-assembly output

Inconsistent fit-up and shortages of assemblies ready to weld can reduce arc-on time and throughput. More available robotic welding time therefore need not produce more completed assemblies. Capacity estimates should retain fitting, loading and welds outside the robot’s assignment instead of treating every existing welding labor hour as removable.

Begin with assembly families that combine sustained demand and demonstrable joint coverage. Compare the proposed completed-assembly output with current output using the actual production mix and remaining manual operations. A plant limited by fitting or inaccessible welds may need a different intervention from a plant whose robot-accessible welding workload is the principal constraint.

Each proposed installation should receive an application-specific safety assessment. ANSI/A3 R15.06-2025 addresses industrial robots and robot applications and cells in Parts 1 and 2; ANSI/A3 R15.06-3-2025 provides user guidance. A shared machine family does not establish identical safeguards or operating practices across plants.

The market development supports renewed attention to robotic investment, not uniform purchases. Sequence welding expansion around sustained demand, usable coverage and completed output, while preserving manual capacity where it remains appropriate.

If you are considering a first robotic welding installation or a multi-plant expansion, call me with representative assembly drawings and available 3D models, production mix and batch sizes at each location, and current output and remaining manual work. I can help assess the capacity and labor exposure behind a phased BLOK investment and coordinate an application review with our team, without assuming every plant needs the same cell.
