Fusion Welding

Aerospace Aluminum Fusion Welding Scrap Reduction

In aerospace manufacturing, weld quality and consistency directly impact product reliability, delivery performance, and overall cost. Aluminum fusion welding, particularly GTAW (TIG), presents unique challenges due to sensitivity to technique, cleanliness, and parameter control. This case study highlights how Amer Welding Solutions supported an aerospace manufacturer in improving welding performance by reducing scrap, stabilizing the process, and strengthening overall production consistency.

The Challenge

The customer was producing aluminum aerospace components using GTAW (TIG welding) and was experiencing:

While welding procedures (WPS) were available, there was a noticeable gap between documented requirements and actual shop floor execution. This resulted in inconsistent outcomes and reduced process reliability.

Results

15% reduction in scrap rate

Improved weld consistency across operators

Reduced rework and production interruptions

Increased throughput and process stability

Improved adherence to welding procedures

Technical Assessment

Amer Welding Solutions conducted a detailed evaluation of the welding process, focusing on both engineering requirements and real shop-floor conditions. The assessment included:

Review of WPS and PQR alignment with production welding
Observation of operator welding techniques and consistency
Evaluation of joint preparation and cleanliness practices
Verification of shielding gas selection and flow control
Identification of variation in: Heat input, Travel speed, Filler metal application
Review of in-process and final inspection criteria

The key finding was that the process lacked standardization at the execution level, even though procedures existed.

Business Impact

Improved on-time delivery performance
Increased customer confidence in weld quality
Reduced cost associated with scrap and rework
Stronger foundation for aerospace compliance and audit readiness
Identification of variation in: Heat input, Travel speed, Filler metal application
Review of in-process and final inspection criteria

This case demonstrates how focused improvements in welding process control can directly enhance both quality performance and operational efficiency.

Solution Implemented

Amer Welding Solutions worked closely with the customer’s team to implement targeted improvements focused on process control and repeatability. Key actions included:

Aligning WPS requirements with actual production practices
Standardizing welding parameters and acceptable ranges
Providing hands-on operator guidance to improve consistency
Establishing clear expectations for: Torch angle, Travel speed, Filler metal usage
Reinforcing cleanliness requirements prior to welding
Introducing in-process inspection checkpoints
Improving communication between engineering, welding, and quality teams

The approach was practical and shop-floor focused, ensuring changes were easy to implement and sustain.

Why It Matters

In aerospace applications, aluminum welding requires a high level of control due to:

By improving process consistency and aligning execution with engineering requirements, manufacturers can significantly reduce variability and improve overall reliability.
