In addition to our broad menu of capabilities, O’Neal Manufacturing Services (OMS) offers in-house secondary capabilities and services to meet customer requirements on plate fabrications and sub-assemblies. Examples of these services include:

Blasting

Blasting is the process used to smooth, shape, or roughen a surface or remove surface contaminants.

Metal Finishing

Metal finishing changes the surface of an object for the purpose of improving its appearance and/or durability.

Metal Sawing

Metal sawing is the process of using a saw blade to cut a large metal workpiece into smaller pieces.

At O’Neal Manufacturing Services (OMS), we understand the importance of consistency and efficiency – especially when it comes to complex parts with tight tolerances. Our leveling & flattening equipment helps make this possible. OMS’ equipment includes one of the largest hydraulic parts levelers in North America and leading FlatMaster equipment. We’re able to provide parts leveling up to 1.675” thick and 78.7” wide. Our skilled, certified teams are experienced in flattening and leveling parts cut from metal plate & sheet, with varying shapes & sizes as well as tight tolerance hold profiles.

At O’Neal Manufacturing Services (OMS) we utilize Kanban, a management system that aims to help you visualize work and maximize efficiency while constantly improving. This allows us to actively improve supply chains for our original equipment manufacturer (OEM) customers by using Kanban as a tool for lean manufacturing—helping prevent a surplus of inventory by initiating production only to restock empty reserves.

Improve Operations and Lower Production Costs

When outsourcing some or all of your manufacturing, it is recommended to choose a supplier that offers Kanban programs. Kanban improves operations, lowers overhead costs, and standardizes production goals leading to increased efficiency and improved flow, teamwork, and responsiveness to changes in demand.

OMS is not only committed to producing the highest quality, most accurate parts for our OEMs, we can actively improve their supply chains by providing processes and equipment that make production more efficient and cost-effective. This sets us apart from other manufacturers.

Welding Methods Explained

MIG Welding

Metal inert gas or MIG welding is one of the most versatile processes used to join metals.  MIG welding incorporates a shielding gas with a solid electrode wire that is continuously fed into a hand-held MIG torch. The heat produced from an electric arc melts the wire onto the base material creating a weld pool that fuses them together. Both skilled welders and robotic welding machines perform a variety of MIG welds on steel or stainless steel.  This welding method is preferable for thicker material and for fill passes in thick-wall pipe welds.

TIG Welding

TIG or tungsten inert gas welding is ideal for specific penetration on thinner materials requiring precision welds. This welding method incorporates a tungsten electrode arc from the welding torch with a separate metal filler rod. A small, intense arc heats the base metal until it melts, then the filler rod is dipped into the melted pool, and the two pieces begin to join. TIG welding arcs produce less spatter than MIG arcs, offering a good amount of control for the user and a cleaner finish.

Stick Welding

The stick welding method is one of the simplest and most cost-efficient processes of joining materials.  A flux-coated rod and the metal workpieces are melted together at one point to form a weld pool.  As the pool cools, the joint between the two metals forms a sturdy bond. No shielding gas is needed in this process which is widely used on steel, aluminum, nickel, and copper alloys.  Stick welding tends to create molten splatter, and finished products require more cleaning and sanding than other arc welding methods.

Stud Welding

Stud welding joins a fastener to a metal object or surface by way of an electric arc.  As the fastener heats up and the surface area melts, the fastener is manipulated into position and the weld is formed.  There are two types of stud welding; drawn arc and capacitor discharge. Drawn arc welding required both the fastener and the base material to be heated.  Capacitor discharge creates some of the fastest stud welds, using a stud gun to trigger the weld charge and melt the fastener head to the base material simultaneously.

Robotic Welding

O’Neal Manufacturing Services offers robotic welding to automate both the welding process and the handling of the base metal part.  Skilled welders maintain programming control while the robotic technology scans, positions, and welds parts in a repetitive, uninterrupted workflow. Often used in mass production, robotic welding is well suited for short welds with curved surfaces.

Laser Welding

The term laser welding means light amplification by stimulated emission of radiation.  Laser welding generates a highly concentrated beam of light to produce a metal-to-metal weld with no filler material needed. The beam of light is amplified and directed on the material seams until they reach a melting point which fuses the two surfaces together.  Gas, solid-state, and fiber are the most common types of laser welding technologies.  Each produces a cleaner edge with improved perpendicularity than other forms of flame cutting.  The laser welding process is excellent for cutting carbon steel, low alloy steel, aluminum, and stainless-steel material from light gauge to heavier gauge thickness and plate.

Projection Welding

Unlike arc welding, projection is a form of resistance welding.  This method uses pressure and an electrical current to join metal parts.  Projections or dimples are manufactured on the base material.  As parts are brought together, an electrical current is focused on the projection points, which generates heat through an electric pulse in these specific locations. Force is applied from upper and lower plateaus connecting the parts together as the current is applied.  Projection welding is commonly used to weld connectors such as bolts, nuts, and screws to base metal parts.

Resistance Spot-welding 

Spot welding is another form of resistance welding.  This method utilizes a pair of water-cooled copper electrodes to clamp two workpieces together and pass an electric current between them.  The electrical resistance of the part material generates enough heat to form a weld nugget that bonds the pieces together.  This type of welding is used to manufacture pipe, tubing, and smaller structural sections, and is popular in the automotive industry as well as others manufacturing products made of thinner gauge materials.

From simple shapes to complex parts, oxy fuel cutting can cut almost all grades of carbon and alloy steel plate. It is best utilized with heavy gauge plate with a maximum thickness of 12 inches. There are several advantages of the oxy fuel cutting process. It’s use of several preheating flames allows for the direction of cuts to be changed seamlessly, making cleaner cuts. Large and thick sections of material can also be cut more efficiently as the oxy fuel cutter is light and quiet, requiring little effort to use.
