Laser Cleaning For Surface Preparation For Pre-Weld And Pre-Bonding Applications

Laser Cleaning for Surface Preparation for Pre-Weld and Pre-Bonding Applications
Available for download

Laser cleaning has been an effective tool in manufacturing and industrial applications for over 20 years. Cleaning, as well as cutting and welding, has shown vast improvements in repeatability and precision with the use of laser technology [4]. Previous bonding techniques such as mechanical fixturing and welding can be inconsistent and cause issues like increased structural weight, decreased structural integrity, galvanic corrosion, and many more potential failures [5]. Laser cleaning may propose a viable option for adhering materials to reduce weight and increase repeatability. Welding practices continue to develop to reduce both weld thickness and porosity. Porosity in welds is typically caused from failure to prepare the surface adequately [1]. Failures in both welding applications and adhesive bonding applications can be reduced with the use of laser technology.

As laser cleaning continues to gain popularity as a source for surface prep and coating removal, this study will explore the use of laser ablation to remove contaminant oxidation and other contamination from metallic substrates. Laser cleaning systems can target coatings while having a minimal impact to the metallic substrates. This study will demonstrate how using laser cleaning technology can improve the surface free energy of a substrate and promote successful welding and adhesive bonding. The process of ablation is created when the laser wavelength is absorbed into the contaminant or oxidation coating. Material properties drive the absorption abilities for substrates and coatings to absorb different wavelengths of laser energy. This high energy exchange causes the contaminants to rapidly change from a solid to a gas, which is eventually vacuumed away. Readily available laser cleaning systems are currently found in industrial, automotive, and aerospace fields and are being utilized for everyday operations. This study explores and explains the feasibility of using laser cleaning as an adequate preparation technique for cleaning before welding and adhesive bonding.

As onshore pipeline rights-of-way become more congested and urban sprawl increases, the number of horizontal directional drills (HDDs) will likely increase. HDD is a trenchless pipeline installation method that requires drilling a larger pilot hole where the mainline pipe can be subsequently pulled through the drilled hole. However, HDDs have an increased probability for coating damage, even when coated with traditional mill or field applied abrasion resistant overcoat (ARO). This coating damage includes abrasion, impact, gouging, denting, tearing, bending, etc. and that damage may exist for the life of the pipeline due to an HDD being inaccessible for future maintenance.

The bulk of a pipeline coating is shop applied and those processes are typically automated. Because
the automation of pipeline coating has so many controls, there is little need to address the inspection on the body of the mainline coatings. As such, this paper will address inspection of pipeline specific coating types and their unique considerations in a field environment. It will address concerns around tie-ing into other coating types and compatibility.

Very often the life of a corrosion protection paint coating system will not meet the design life of the steel structure it is supposed to protect. Decisions about coating selection are usually focusing on the costs for the initial construction, ignoring the certain future maintenance costs. The total cost of ownership includes the initial cost plus the maintenance, operating and finance costs over the life of a structure. Repeated maintenance operations, and resulting downtime, can add significantly to the total cost of ownership.
