JOIN THE COMMITTEE/SUBCOMMITTEE

The G1 Committee seeks volunteers to participate in its standards development process. The committee is recruiting all types of members as well as members with specific interests (Consultants and General Interest) in regard to the committee’s scope. Contact Jennifer "Jen" Padron to learn more about this committee’s work and/or complete the Technical Committee Application.

As part of the standards development process, joining this committee will give you access to Accuris Engineering Workbench to streamline your workflow.

PUBLISHED DOCUMENTS

AWS G1.1M/G1.1:2006

Guide to Ultrasonic Assembly of Thermoplastics (Historical)

This guide details the ultrasonic equipment and the processes used in industry for fabricating thermoplastic parts, including welding, staking, swaging, insertion, forming, degating, cutting, and trimming. Included are sections on safety, equipment setup, joint and part design, testing, and process optimization.

AWS G1.2M/G1.2:1999

Specification for Standardized Ultrasonic Welding Test Specimen for Thermoplastics

You need this document to help minimize variations in the geometry, welding, and testing of the ultrasonic welding test sample for thermoplastics. Detailed figures show tolerances on critical dimensions that may affect weldability. Use this specification for studies on the ultrasonic welding of thermoplastics, weldability studies, and optimizations.

AWS G1.6:2022

Specification for the Training, Qualification, and Company Certification of Thermoplastic Welding Inspector Specialists and Thermoplastic Welding Inspector Assistants

This specification defines the requirements and program for an employer (company) to train, qualify, and company certify Thermoplastic Welding Inspector Specialists and Thermoplastic Welding Inspector Assistants to contract or industry-specific inspector standards. The program is developed as a written practice and controlled by an employer. The qualification requires documentation of experience, training, and satisfactory completion of an examination. The examination tests knowledge of welding processes, welding procedures, welder qualification, destructive testing, nondestructive testing, terms, definitions, symbols, reports, records, safety, and responsibility as specifically applied by the contract or industry standards applicable to the employer.

AWS G1.10M:2016

Guide for the Evaluation of Hot Gas, Hot Gas Extrusion, and Heatedtool Butt Thermoplastic Welds

This standard lists and describes flaws and defects in hot gas, hot gas extrusion, heated tool butt fusion, socket fusion, electrofusion, and flow fusion welded joints in thermoplastics. Its intent is to make possible a generally valid evaluation giving consideration to graded quality requirements. This standard encompasses the classification, requirements, testing, evaluation, and acceptance of the welds. Details in recording engineering data are described. Tables illustrating cracks, voids, solid inclusions, lack of fusion, flaws and defects of shape, and other flaws and defects in thermoplastic welds are included. Flaw and defect features with descriptions and illustrations are compiled into tables to aid in the evaluation of welds.
