Weldlogic Applications

For Medical Industry

Medical devices such as catheter guidewires, arthoscopic cutting tools, surgical baskets, implantable battery devices, heart valves, biopsy needles and a wide array of  tools that require a joining method as part of their manufacturing can now be automated with computerised precision arc welding. Weldlogic provides reliable metal joining processes to facilitate the need for low level assembly heat to minimize mechanical distortion to the finished product. For example, a Dutch manufacturer uses Weldlogic pulsed arc equipment to produce implantable pharmaceutical delivery systems called portals, used worldwide for treatment of cancer, AIDS and chronic pain.

These portals consist of a hollow reservoir with a thick, pliable membrane for the introduction of medication, or removal of body fluid, by means of a hollow needle. The portal, surgically implanted, is attached to a catheter for the transport of fluid to a vein. A precision TIG welding system is used to attach this reservoir to the connection system.

For Sensor Industry

Transducer assemblies, such as diaphragms to bodies and cases and connectors to housings, must be hermetically sealed and mechanically sound. The joining of such components require a low heat input process to avoid internal damage and distortion, yet provide a strong, consistent weld. Weldlogic has developed several processes with impact for the sensor’s market and has taken the transducer industry full circle with the introduction of laser technology to compliment the micro-tig and plasma product lines. The full compliment of micro-joining processes available through Weldlogic demonstrates our ongoing commitment to this industry.

Bellows

Metal bellows have many uses, such as conducting gas or liquid between two members which may vibrate or be susceptible to shifting. Bellows are also used in instruments in which the bellow can respond to pressure differences by expanding or contracting. Weld consistency is obviously of great importance. It is also obvious that weld speed is important because of the thousands of feet many bellows companies must weld everyday. Weldlogic’s Pulsed Micro-Arc, when set properly, increases weld speed by 40% while at the same time creating a consistent weld bead. The Weldlogic Arc is stable at less than ½ an ampere, well under industry standards that require extremely accurate welds at 1 ampere or less.

Tool, Die and Mould Repair

Both the Weldlogic Micro-Arc welding power supply and YAG Lasers offer the ability to reduce tool repair costs by making accurate low temperature weld repairs.  The ability of the Weldlogic power supplies to gently start a low amperage arc and make repairs with minimal heat input has provided customers with significant cost savings.  With conventional Tig Welding repairs, many tools have to be replaced because of the distortion caused by excessive heat input.

The Micro - Arc power supply and laser generates small weld pools thus keeping the Heat Affected Zone to an absolute minimum.  The weld pool being so small enables the operator to deposit much smaller filler wires, distortion is controlled and final expensive machining costs are reduced.

UPS - Twin Station Seamer

In this system a single AWS-150 power supply is shared between two Precision UPS-12 seamers via a dual head switching box.  The system allows one part to be welded whilst the other machine is being loaded.

Welding Press Up to 1.5 Tonnes

Weldlogic Europe were commissioned to provide a welding press to allow high performance battery cells to be encapsulated whilst rotating under loads up to 1.5 Tonnes.

Corner Welding

These corner welds for the tops of filing cabinets and cupboard tops were traditionally welded utilising gas welding techniques and then fettled back by hand before painting.  This automatic system
developed by Weldlogic allows the corners to be welded automatically without any need for dressing and goes straight to the paint shop after welding. Weldlogic have supplied both single corner and dual corner welding stations.
