Soldering and Riveted joints with
More potential in every Design
Determine the appropriate dimensions for rivets and Soldering joints , reliably assess stresses
, and document technical results in a transparent manner.
Use joining techniques specifically where they can best demonstrate their strengths
Riveting and Soldering joints are particularly useful when thin-walled parts, temperature-sensitive components, or special manufacturing conditions limit the use of traditional joining methods.
MDESIGN Supports the calculation of typical riveted and Soldering joints , from sizing to strength verification. This allows users to more quickly assess suitable joint types, evaluate loads in a targeted manner, and make more informed comparisons of design alternatives.
Establish standards, accelerate engineering
MDESIGN provides a consistent basis for calculations across the entire team. Structured data entry, centrally maintained calculation bases, and consistent documentation ensure that results remain traceable and comparable across projects.
For over 40 years, MDESIGN has been helping companies calculate and design technical components—today with more than 35,000 users worldwide.
Determine dimensions and load-bearing capacity directly
For riveted and bolted connections (soldering joints), different dimensions are key depending on the design. While for riveted connections (riveted joints), factors such as rivet diameter, rivet length, number of rivets, and hole clearance are crucial, soldering joints are evaluated based on normal, shear, and torsional stresses. MDESIGN organizes these calculations in a structured manner and shows which dimensions are required and how much stress the connection is actually subjected to.
Take into account the material properties appropriate for the joint
The load-bearing capacity of a riveted or brazed joint depends directly on the materials used and their allowable properties. MDESIGN provides a comprehensive materials database containing relevant properties for various fasteners and material groups.
Factors taken into account include shear strengths from soldering joints, allowable shear stresses, hole wall pressures, and rivet materials. In addition, users can add their own materials, internal parameters, and company-specific material data, save them, and use them consistently for recurring calculations.
This allows standard materials and company-specific specifications to be mapped in a shared database, and connections to be evaluated more closely in line with the actual design.
Use the results for further design
MDESIGN systematically compiles the relevant stresses, load-bearing capacities, and required dimensions. This not only makes it possible to verify whether a connection is adequately dimensioned, but also to identify which parameter determines the design.
Design engineers can use this information to make specific decisions: adjust the number of rivets, change the diameter, increase the soldering area, or choose a different type of joint. This makes it easier to compare different variants and allows for more targeted design changes.
01
Automatically generated charts
All relevant results are presented clearly. Rivet load-bearing capacity, required number of rivets, hole wall pressure, and solder joint stresses indicate the limits that apply to each joint and where adjustments may be necessary.

02
Intuitive user interface
A clearly organized interface, intuitive input options, help texts, and predefined calculation formulas simplify the processing of various riveting and soldering joints. With aiven, an AI assistant is also available directly within the workflow—which is particularly helpful when specific calculation scenarios occur only rarely.
