Disruptive Production via Wire Arc Additive Manufacturing (WAAM) Technology: Printing pressure vessel in a single set-up

Pressure vessels are essential in various industries, from aerospace and automotive to oil&gas. They are critical in containing fluids or gases under pressure, making them vital for safety and operational efficiency. Traditional manufacturing methods for pressure vessels, such as forging and welding, often come with design flexibility, production speed, and cost-effectiveness limitations. However, these constraints are being redefined with the advent of Wire Arc Additive Manufacturing (WAAM) technology. WAAM offers a revolutionary approach to pressure vessel fabrication, providing unparalleled flexibility, speed, and cost-effectiveness compared to conventional methods. This article will explore how WAAM technology transforms pressure vessel manufacturing and its potential impact across various industries.

“Basics of WAAM Technology”

WAAM is an advanced manufacturing technique that utilises an electric arc to melt metal wire, depositing it layer by layer to create three-dimensional objects. WAAM offers several advantages over traditional manufacturing methods, including increased design flexibility, reduced material waste, and shorter lead times. By eliminating the need for expensive tooling and reducing machining requirements, WAAM significantly lowers production costs while efficiently fabricating complex geometries.

“Understanding WAAM Technology and Its Advantages in Pressure Vessel Production”

Pressure vessels, designed to hold fluids or gases under significant pressure, are vital in various industries. Traditionally, their fabrication relied on methods like forging and welding, which often needed more design flexibility and incurred high costs. However, a transformative shift has occurred with the advent of WAAM technology.
WAAM offers several critical advantages for pressure vessel production. Firstly, WAAM enables enhanced design flexibility, allowing for the fabrication of complex geometries that were previously challenging or impossible with traditional methods. Additionally, WAAM reduces lead times by eliminating the need for tooling and reducing machining requirements. This efficiency contributes to significant cost savings, making WAAM an economically viable solution for pressure vessel fabrication.

“MetalWorm Utility”

MetalWorm, a leading system manufacturer pecializing in additive manufacturing solutions, recently undertook a project in pressure vessel fabrication using WAAM technology. This case study explores the successful implementation of WAAM in producing a pressure vessel with unique specifications and the advantages it brought to the production process.
MetalWorm put a vital task with fabricating a pressure vessel varying in diameter from 60 mm to 300 mm and standing at a height of 495 mm. Traditional manufacturing methods posed challenges in achieving the desired design variations and dimensions while maintaining cost-effectiveness. To address these issues, MetalWorm turned to WAAM technology for its unparalleled flexibility and efficiency.
Utilising WAAM, MetalWorm precisely melted ER5356 welding wire, depositing it layer by layer to build the intricate structure of the pressure vessel. This process enabled MetalWorm to achieve the varying diameters and fixed heights required for the pressure vessels precisely and accurately.
The implementation of WAAM technology brought several critical advantages to the production process for MetalWorm’s pressure vessel. By eliminating the need for tooling and minimising machining requirements, WAAM significantly shortened the production lead times. From start to finish, the printing process took only 8.5 hours, optimising project timelines and delivery schedules. Moreover, the reduction in material waste and the efficiency of the printing process resulted in substantial cost savings.
