Job Description:

Your Work Shapes the World at Caterpillar Inc.

When you join Caterpillar, you're joining a global team who cares not just about the work we do – but also about each other.  We are the makers, problem solvers, and future world builders who are creating stronger, more sustainable communities. We don't just talk about progress and innovation here – we make it happen, with our customers, where we work and live. Together, we are building a better world, so we can all enjoy living in it.

The Overhaul Welder IV position is designated for highly skilled, senior‑level welders who demonstrate expert proficiency in MIG and TIG welding of fittings, piping, sheet metal, and complex components. This role performs advanced fabrication, repair, and remanufacturing of metal parts and is relied upon to execute critical, high‑complexity weld operations that directly impact product quality, safety, and delivery.

Welder IV employees serve as technical leaders on the shop floor, capable of independently planning and executing complex welding tasks, troubleshooting weld‑related issues, mentoring less experienced welders, and supporting production, test, and assembly operations with minimal oversight.

Employees in this role work both independently and collaboratively, providing technical guidance to peers while following direction from team leads, supervisors, and managers. The Overhaul Welder IV is expected to interpret complex drawings, welding procedures, and engineering requirements and to make sound technical decisions to resolve weld‑related challenges without compromising quality or safety.

This role routinely works on high‑complexity parts and assemblies with tight tolerance requirements and minimal engineering or senior support. Welding work performed by Welder IV employees is expected to require little to no rework and often serves as the benchmark for quality and workmanship within the value stream.

Welder IV employees work with a wide range of materials including aluminum, mild steel, alloys, stainless steel, and high‑temperature aerospace alloys. They operate advanced welding equipment and associated tools and are expected to understand heat input, distortion control, joint design, and metallurgical considerations associated with remanufactured components.

Employees must pass and maintain all required welding qualification tests and demonstrate mastery of welding procedures. They must be proficient welding in all positions and adaptable to varied and challenging work environments.

Work may be performed on the manufacturing shop floor, in engine test cells, disassembly areas, or other active work environments. Employees in this role are expected to recognize hazards, model safe work practices, and actively support the development of lower‑level welders through coaching and knowledge sharing.

Candidates may be required to complete a welding test prior to hire or advancement to demonstrate advanced proficiency.

Equipment Utilized

Employees in this role may be required to operate, set up, and adjust the following equipment:

• Welding equipment for GTAW, GMAW, FCAW, and GMAW‑P processes

• Fabrication equipment such as saws, plasma cutters, manual lathes, and drill presses

• Precision measurement tools and gauges for inspection and verification

• Forklifts, cranes, or transporters for handling large or complex components

• Computers for production order completion, documentation, and required training

• Other specialized equipment required to support advanced welding and fabrication tasks

What you will do:

• Comply with all Solar Turbines Environmental, Health, and Safety (EHS) programs, regulations, policies, and best practices; consistently demonstrate proper use of PPE and safety equipment

• Perform advanced welding in accordance with AWS D1.1 or ASME Section IX (B31.3/B31.8) standards and comply with PED requirements when specified

• Execute complex weld repair and remanufacturing of production parts with minimal supervision

• Provide urgent weld repair, fastener extraction, and rework support to production, test, and assembly areas

• Independently inspect and verify work to ensure compliance with procedures, specifications, and quality standards

• Identify and resolve welding process issues; recommend improvements to tooling, fixtures, or procedures when appropriate

• Serve as a technical resource and mentor to lower‑level welders; assist with training and qualification efforts

• Maintain accurate production logs and documentation
