We have always had a strong professional focus on welding performance for the best results; working with our customers to determine the best welding products to use in the right applications to achieve the best results, first time.

This Welding Assistance Resource Section is here to offer general welding advice and information to the wider welding community. 

Very simply, a synergic welding machine refers to a machine that automatically sets the welding parameters according to the material type, thickness, filler metal selected by the user. The machine sets the volts, wire feed speed (amperage), etc according to the information in the programmes stored in the memory of the machine. To explain this a bit more, let’s recap welding technology basics.

Digitizing data, the downloading, sharing, and analyzing of it is a cornerstone of Industry 4.0. So what does that mean for welding workshops, in the manufacturing and fabrication industries?

"What gets measured, can be managed."

Consider if you had real-time figures from the shop floor such as arc on times, operating duty cycles, the parameters used on an individual weld; you can use this data to target and drive improvements in productivity and quality control. Drill down to individual machines or combine data from a number of machines in a section to identify inefficiencies, or look at total costs across the workshop and use this information to assist quotes for the next job.

LORCH of Germany developed LORCH CONNECT with two essential prerequisites: it had to be simple and of immediate practical benefit to the customer. It is also the most cost-effective welding data digitalisation network system available in NZ today. Access through your own customer portal is free for the first year and then a small monthly fee per machine applies. Give us a call on 09634 1948 to learn more.

The range of LORCH Mig welding machines is a good example of where synergic control is heading in the Industry 4.0 era. Made in Germany these are highly flexible, modular systems which can be built to order from 300A to 500A outputs, compact or remote wire feed, gas or water-cooled, and with three different operating control panels to choose from.

What is heat input, and how does it affect the quality of welds?

Heat input can be referred to as "the electrical energy supplied by the welding arc to the workpiece."

In practice, however, heat input can approximately ― if the arc efficiency is not taken into consideration ― be characterised as the ratio of the arc power supplied to the electrode to the arc travel speed, as shown in the following equation.

Metal Cored Wires vs Solid Wire

"I've always used solid wire - works fine, does the job. Why change?"

A typical comment we often hear, however… Change is definitely worth thinking about!

Depending on the application, using metal cored wire (MCW) can generate significant cost savings in conventional gas metal arc welding (GMAW) processes. It is ideal for robotic welding but is also suitable for so much more.

How to calculate welding consumption

We recommend you to use the following diagrams for a quick estimation of the consumption of welding consumables for welding ferritic steel butt joints and fillet joints respectively.

Please follow the examples indicated by gray arrows in the figures.

Essential Factors in Gas Shielded Metal Arc Welding

Nowadays, gas shielded metal arc welding (GSMAW) is widely used in various constructions such as steel structures, bridges, autos, motorcycles, construction machinery, ships, offshore structures, pressure vessels, and pipelines due to high welding efficiency.

Advantages of Downhill Welding

What advantages are there in downhill welding and how should it be used, compared with uphill welding in GMAW and FCAW?

As you may know, we use either downhill or uphill welding in the vertical position. Downhill welding is carried out with a downward progression, conversely, uphill moves in an upward progression. Downhill welding is often used for fillet welding of steel sheets due to the following advantages over uphill welding.

Design of Structural Fillet Welds

Fillet Weld Legs Determine Size and Throat of Fillet Welds 

In heavy machinery, ships, and buildings, extensive frameworks and intricate angles may be composed of many kilometres of welded joints. Among them, fillet welds are used to join corners, Ts. and lap joints because they are more economical than groove welds. That is, fillet welded joints are simple to prepare from the standpoint of edge preparation and fit-up.

How to achieve welding efficiency

The biggest gains for your business can be made by improving welding operator efficiency to reduce your single biggest cost - labour.
